# The Rust toolchain officially used by this project for development and CI.
|
|
#
|
|
# We pin to an exact version rather than `stable`, so that we get consistent
|
|
# results across local development and CI runs, particularly for clippy
|
|
# and other checks that change from release to release. Dependabot's
|
|
# `rust-toolchain` ecosystem bumps it as new releases become available
|
|
# (see .github/dependabot.yml).
|
|
#
|
|
# Note that this is not the MSRV; that's separately specified; see
|
|
# docs/reference/msrv-policy.md.
|
|
#
|
|
# For CI authors: install this version via `rustup toolchain install`
|
|
# (no toolchain name, which causes rustup to honor the version in this
|
|
# file), passing `--profile minimal`. Note that in this nameless form rustup
|
|
# silently ignores `--target` and `--component`; add extra targets and
|
|
# components afterwards with `rustup target add` / `rustup component add`.
|
|
# The components listed below are added on top of whichever profile is
|
|
# chosen, so the only thing the default profile would add is rust-docs:
|
|
# roughly 900 MB across some 66k files that nothing in CI reads, and slow
|
|
# to unpack on Windows runners.
|
|
# This file deliberately doesn't set `profile = "minimal"` itself, so a
|
|
# local install still gets the docs; named installs (MSRV, nightly) need
|
|
# the flag anyway. A job that deliberately needs a different toolchain installs
|
|
# it by name and then runs `rustup override set <toolchain>`; that override
|
|
# takes precedence over this file. Don't use dtolnay/rust-toolchain:
|
|
# it selects its toolchain with `rustup default`, which this file
|
|
# silently overrides.
