[toolchain]
# Single source of truth for the Rust version used everywhere: local builds,
# CI, and the cross-rs build containers. `stable` tracks the latest release;
# cross installs this same toolchain inside its container via rustup.
channel = "stable"
components = ["rustfmt", "clippy"]
# All release targets are listed so rustup installs their std automatically.
# This matters when a cross-rs / osxcross image is used directly as a build base
# (e.g. in the Earthfile), where nothing runs `rustup target add`. Installing a
# target's std is host-independent; only *linking* needs the matching toolchain
# (cross-rs images for Linux/Windows, osxcross for the Apple targets).
