rustup installs The Rust Programming Language from the official
|
|
|
|
release channels, enabling you to easily switch between stable, beta,
|
|
|
|
and nightly compilers and keep them updated. It makes cross-compiling
|
|
|
|
simpler with binary builds of the standard library for common platforms.

|
Many `rustup` commands deal with *toolchains*, a single installation
|
|
|
|
of the Rust compiler. `rustup` supports multiple types of
|
|
|
|
toolchains. The most basic track the official release channels:
|
|
|
|
'stable', 'beta' and 'nightly'; but `rustup` can also install
|
|
|
|
toolchains from the official archives, for alternate host platforms,
|
|
|
|
and from local builds.
|
|
|
|
|
|
|
|
Standard release channel toolchain names have the following form:
|
|
|
|
|
|
|
|
<channel>[-<date>][-<host>]
|
|
|
|
|
|
|
|
<channel> = stable|beta|nightly|<version>
|
|
|
|
<date> = YYYY-MM-DD
|
|
|
|
<host> = <target-triple>
|
|
|
|
|
|
|
|
'channel' is either a named release channel or an explicit version
|
|
|
|
number, such as '1.8.0'. Channel names can be optionally appended with
|
|
|
|
an archive date, as in 'nightly-2014-12-18', in which case the
|
|
|
|
toolchain is downloaded from the archive for that date.
|
|
|
|
|
|
|
|
Finally, the host may be specified as a target triple. This is most
|
|
|
|
useful for installing a 32-bit compiler on a 64-bit platform, or for
|
|
|
|
installing the [MSVC-based toolchain] on Windows. For example:
|
|
|
|
|
|
|
|
rustup toolchain install stable-x86_64-pc-windows-msvc
|
|
|
|
|
|
|
|
For convenience, elements of the target triple that are omitted will be
|
|
|
|
inferred, so the above could be written:
|
|
|
|
|
|
|
|
$ rustup default stable-msvc
|
|
|
|
|
|
|
|
Toolchain names that don't name a channel instead can be used to name
|
|
|
|
custom toolchains with the `rustup toolchain link` command.";

static OVERRIDE_HELP: &str = r"

|
Overrides configure rustup to use a specific toolchain when
|
|
|
|
running in a specific directory.
|
|
|
|
|
|
|
|
Directories can be assigned their own Rust toolchain with
|
|
|
|
`rustup override`. When a directory has an override then
|
|
|
|
any time `rustc` or `cargo` is run inside that directory,
|
|
|
|
or one of its child directories, the override toolchain
|
|
|
|
will be invoked.
|
|
|
|
|
|
|
|
To pin to a specific nightly:
|
|
|
|
|
|
|
|
rustup override set nightly-2014-12-18
|
|
|
|
|
|
|
|
Or a specific stable release:
|
|
|
|
|
|
|
|
rustup override set 1.0.0
|
|
|
|
|
|
|
|
To see the active toolchain use `rustup show`. To remove the override
|
|
|
|
and use the default toolchain again, `rustup override unset`.";

If `--path` argument is present, removes the override toolchain for
|
|
|
|
the specified directory. If `--nonexistent` argument is present, removes
|
|
|
|
the override toolchain for all nonexistent directories. Otherwise,
|
|
|
|
removes the override toolchain for the current directory.";

Configures an environment to use the given toolchain and then runs

the specified program. The command may be any program, not just

rustc or cargo. This can be used for testing arbitrary toolchains
|
|
|
|
without setting an override.
|
|
|
|
|
|
|
|
Commands explicitly proxied by `rustup` (such as `rustc` and `cargo`)
|
|
|
|
also have a shorthand for this available. The toolchain can be set by
|
|
|
|
using `+toolchain` as the first argument. These are equivalent:
|
|
|
|
|
|
|
|
cargo +nightly build
|
|
|
|
|
|
|
|
rustup run nightly cargo build";
