# Stable Rust + cross-compile targets. Targets land under $RUSTUP_HOME for
# the pinned toolchain, so they're always available under `mise exec` — no
# extra `rustup target add` step at setup time.
#
# Xtensa ESP targets are NOT listed here — they use the self-contained `esp`
# toolchain populated by `mise run esp-install` (see [tasks] below). That
# toolchain ships its own rust-src for `-Zbuild-std`.

# ESP Xtensa toolchain. `cargo:espup` above only installs the *installer*;
# the actual rustc-esp + xtensa-esp-elf-gcc + esp-clang toolchains are
# populated by `mise run esp-install` (or `just setup`).
#
# espup hardcodes its install root to ~/.rustup/toolchains/esp/ — there's
# no --prefix or --install-dir flag — so the binaries necessarily live
# there. The [env] block below pins the exact PATH and LIBCLANG_PATH so
# every `mise exec` (which the justfile uses for `set shell`) resolves
# the cross-toolchain without depending on espup's stray ~/export-esp.sh.
#
# Bumping versions: edit the version dirs in BOTH [tasks.esp-install] (so
# espup installs the matching crosstool) AND [env] (so the path resolves).
