# Repo-level Cargo configuration.

# Faster linking (OPT-IN)
# ────────────────────────────────────────────────────────────────────────────
# The `openhuman` core crate is very large and links a single ~big rlib, so the
# edit → `cargo check`/`cargo test` inner loop is frequently *link-bound*. A
# faster linker (mold on Linux, lld on macOS) can cut a large slice off every
# incremental relink.
#
# These are intentionally left COMMENTED OUT: an unconditional `linker=` /
# `-fuse-ld=` here would hard-fail every build on a machine that does not have
# the linker installed — including the `pnpm rust:check` pre-push hook. Opt in
# locally by installing the linker and uncommenting the matching block (or, to
# avoid touching this tracked file, copy the block into `$CARGO_HOME/config.toml`
# or a parent-directory `.cargo/config.toml`, which Cargo merges automatically).
#
# ── Linux: mold (recommended) ───────────────────────────────────────────────
#   apt install mold      # or: brew install mold / dnf install mold
#
# [target.x86_64-unknown-linux-gnu]
# linker = "clang"
# rustflags = ["-C", "link-arg=-fuse-ld=mold"]
#
# ── macOS: lld ──────────────────────────────────────────────────────────────
#   brew install llvm     # provides ld64.lld
# Note: recent Xcode ships Apple's new `ld-prime`, which is already fast, so lld
# is often only a marginal win on Apple Silicon — measure before committing to
# it. `sold`/`zld` (older third-party mach-o linkers) are unmaintained/paid.
#
# [target.aarch64-apple-darwin]
# rustflags = ["-C", "link-arg=-fuse-ld=/opt/homebrew/opt/llvm/bin/ld64.lld"]
#
# [target.x86_64-apple-darwin]
# rustflags = ["-C", "link-arg=-fuse-ld=/usr/local/opt/llvm/bin/ld64.lld"]
