# Pins the toolchain so the tools cannot disagree about which rustc they are.
#
# This is not hypothetical: on one machine here `cargo clippy` resolved to a
# stale 0.1.81 shim on PATH while `cargo build` used 1.97, so clippy refused to
# run at all and its output was silently absent from every local check. A lint
# nobody can run is a lint nobody is enforcing.
#
# rustup reads this file. A Homebrew or distro-packaged rust ignores it, so if
# `rustc --version` disagrees with the channel below, that is why.
