# 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"]
