Sered no longer uses blobs as of
https://github.com/serde-rs/serde/pull/2590
As such, there's no longer need for us to pin it.
Note that this doesn't upgrade serde version we use: I am fairly
confident that the blobs are already there are fine, and now I am fairly
confident that all future versions of serde will be fine as well.
serde 1.0.172 and up rely on opaque non-reproducible binary blobs to
function, explicitly not providing a library-level opt-out.
This is problematic for two reasons:
- directly, unauditable binary blobs are a security issue.
- indirectly, it becomes much harder to predict future behaviors of the
crate.
As such, I am willing to go on a limb here and forbid building
rust-analyzer with those versions of serde. Normally, my philosophy is
to defer the choice to the end user, but it's also a design constraint
of rust-analyzer that we don't run random binaries downloaded from the
internet without explicit user's concent.
Concretely, this upper-bounds serde for both rust-analyzer workspace, as
well as the lsp-server lib.
See https://github.com/serde-rs/serde/issues/2538 for wider context.
Fix: a TODO and some clippy fixes
- fix(todo): implement IntoIterator for ArenaMap<IDX, V>
- chore: remove unused method
- fix: remove useless `return`s
- fix: various clippy lints
- fix: simplify boolean test to a single negation
More APIs for `la_arena::IdxRange`
```rust
impl<T> ExactSizeIterator for IdxRange<T>;
impl<T> Arena<T> {
pub fn alloc_many<II: IntoIterator<Item = T>>(&mut self, iter: II) -> IdxRange<T>;
}
```
1. There are no currently ways to get `IdxRange` without manually offseting `Idx`. Providing a method for multiple-allocation simplifies this process and makes it less error-prone.
2. `IdxRange: ExactSizeIterator` makes `iter.zip(range).rev()` possible. Since `Zip: DoubleEndedIterator` requires all its arguments to be `ExactSizeIterator`. It also ease the usage for, eg. `len()`.
3. Fixed a typo.
I noticed that `IdxRange::end` may be invalid. Is it good to return `Idx` instead of `RawIdx`?
