The new methods return/accept `Into<Position>` which can be either a Position or a (u16, u16) tuple.
```rust
backend.set_cursor_position(Position { x: 0, y: 20 })?;
let position = backend.get_cursor_position()?;
terminal.set_cursor_position((0, 20))?;
let position = terminal.set_cursor_position()?;
```
This is a simplification of the public API that is helpful for new users
that are not familiar with how rust re-exports work, and helps avoid
clashes with other modules in the backends that are named terminal.
BREAKING CHANGE: The `terminal` module is now private and can not be
used directly. The types under this module are exported from the root of
the crate.
```diff
- use ratatui::terminal::{CompletedFrame, Frame, Terminal, TerminalOptions, ViewPort};
+ use ratatui::{CompletedFrame, Frame, Terminal, TerminalOptions, ViewPort};
```

Layout::init_cache no longer returns bool and takes a NonZeroUsize instead of usize
The cache is a thread-local, so doesn't make much sense to require
synchronized initialization.
his PR removes the items from the prelude that don't form a coherent
common vocabulary and adds the missing items that do.
Based on a comment at
<https://www.reddit.com/r/rust/comments/1cle18j/comment/l2uuuh7/>
BREAKING CHANGE:
The following items have been removed from the prelude:
- `style::Styled` - this trait is useful for widgets that want to
support the Stylize trait, but it adds complexity as widgets have two
`style` methods and a `set_style` method.
- `symbols::Marker` - this item is used by code that needs to draw to
the `Canvas` widget, but it's not a common item that would be used by
most users of the library.
- `terminal::{CompletedFrame, TerminalOptions, Viewport}` - these items
are rarely used by code that needs to interact with the terminal, and
they're generally only ever used once in any app.
The following items have been added to the prelude:
- `layout::{Position, Size}` - these items are used by code that needs
to interact with the layout system. These are newer items that were
added in the last few releases, which should be used more liberally.
Updates the requirements on termion to permit the latest version.

BREAKING CHANGE: Changelog:
<https://gitlab.redox-os.org/redox-os/termion/-/blob/master/CHANGELOG.md>
A change is only necessary if you were matching on all variants of the
`MouseEvent` enum without a
wildcard. In this case, you need to either handle the two new variants,
`MouseLeft` and
`MouseRight`, or add a wildcard.

`List::start_corner` was deprecated in v0.25. Use `List::direction` and
`ListDirection` instead.
```diff
- list.start_corner(Corner::TopLeft);
- list.start_corner(Corner::TopRight);
// This is not an error, BottomRight rendered top to bottom previously
- list.start_corner(Corner::BottomRight);
// all becomes
+ list.direction(ListDirection::TopToBottom);
```
```diff
- list.start_corner(Corner::BottomLeft);
// becomes
+ list.direction(ListDirection::BottomToTop);
```
`layout::Corner` is removed entirely.

Any iterator whose item is convertible into `Row` can now be
collected into a `Table`.
Where previously, `Table::new` accepted `IntoIterator<Item = Row>`, it
now accepts `IntoIterator<Item: Into<Row>>`.
BREAKING CHANGE:
The compiler can no longer infer the element type of the container
passed to `Table::new()`. For example, `Table::new(vec![], widths)`
will no longer compile, as the type of `vec![]` can no longer be
inferred.
Any iterator whose item is convertible into `Line` can now be
collected into `Tabs`.
In addition, where previously `Tabs::new` required a `Vec`, it can now
accept any object that implements `IntoIterator` with an item type
implementing `Into<Line>`.
BREAKING CHANGE:
Calls to `Tabs::new()` whose argument is collected from an iterator
will no longer compile. For example,
`Tabs::new(["a","b"].into_iter().collect())` will no longer compile,
because the return type of `.collect()` can no longer be inferred to
be a `Vec<_>`.
In https://github.com/ratatui-org/ratatui/pull/660 we introduced the
segment_size field to the Table struct. However, we forgot to update
the default() implementation to match the new() implementation. This
meant that the default() implementation picked up SegmentSize::default()
instead of SegmentSize::None.
Additionally the introduction of Table::default() in an earlier PR,
https://github.com/ratatui-org/ratatui/pull/339, was also missing the
default for the column_spacing field (1).
This commit fixes the default() implementation to match the new()
implementation of these two fields by implementing the Default trait
manually.
BREAKING CHANGE: The default() implementation of Table now sets the
column_spacing field to 1 and the segment_size field to
SegmentSize::None. This will affect the rendering of a small amount of
apps.
Previously, `patch_style` and `reset_style` in `Text`, `Line` and `Span`
were using a mutable reference to `Self`. To be more consistent with
the rest of `ratatui`, which is using fluent setters, these now take
ownership of `Self` and return it.
* feat: accept Color and Modifier for all Styles
All style related methods now accept `S: Into<Style>` instead of
`Style`.
`Color` and `Modifier` implement `Into<Style>` so this is allows for
more ergonomic usage. E.g.:
```rust
Line::styled("hello", Style::new().red());
Line::styled("world", Style::new().bold());
// can now be simplified to
Line::styled("hello", Color::Red);
Line::styled("world", Modifier::BOLD);
```
Fixes https://github.com/ratatui-org/ratatui/issues/694
BREAKING CHANGE: All style related methods now accept `S: Into<Style>`
instead of `Style`. This means that if you are already passing an
ambiguous type that implements `Into<Style>` you will need to remove
the `.into()` call.
`Block` style methods can no longer be called from a const context as
trait functions cannot (yet) be const.
* feat: add tuple conversions to Style
Adds conversions for various Color and Modifier combinations
* chore: add unit tests
- The `Line` struct now stores the style of the line rather than each
`Span` storing it.
- Adds two new setters for style and spans
- Adds missing docs
BREAKING CHANGE: `Line::style` is now a field of `Line` instead of being
stored in each `Span`.
The previous name `start_corner` did not communicate clearly the intent of the method.
A new method `direction` and a new enum `ListDirection` were added.
`start_corner` is now deprecated
This allows to build list like
```
List::new(["Item 1", "Item 2"])
```
BREAKING CHANGE: `List::new` parameter type changed from `Into<Vec<ListItem<'a>>>`
to `IntoIterator<Item = Into<ListItem<'a>>>`
This prevents creating a table that doesn't actually render anything.
Fixes: https://github.com/ratatui-org/ratatui/issues/537
BREAKING CHANGE: Table::new() now takes an additional widths parameter.
Previously the default highlight_style was set to `Style::default()`,
which meant that the highlight style was the same as the normal style.
This change sets the default highlight_style to reversed text.
BREAKING CHANGE: The `Tab` widget now renders the highlight style as
reversed text by default. This can be changed by setting the
`highlight_style` field of the `Tab` widget.
Adds a convenience function to create a layout with a direction and a
list of constraints which are the most common parameters that would be
generally configured using the builder pattern. The constraints can be
passed in as any iterator of constraints.
```rust
let layout = Layout::new(Direction::Horizontal, [
Constraint::Percentage(50),
Constraint::Percentage(50),
]);
```
BREAKING CHANGE:
Layout::new() now takes a direction and a list of constraints instead of
no arguments. This is a breaking change because it changes the signature
of the function. Layout::new() is also no longer const because it takes
an iterator of constraints.
This allows passing an array, slice or Vec of constraints, which is more
ergonomic than requiring this to always be a slice.
The following calls now all succeed:
```rust
Table::new(rows).widths([Constraint::Length(5), Constraint::Length(5)]);
Table::new(rows).widths(&[Constraint::Length(5), Constraint::Length(5)]);
// widths could also be computed at runtime
let widths = vec![Constraint::Length(5), Constraint::Length(5)];
Table::new(rows).widths(widths.clone());
Table::new(rows).widths(&widths);
```
