# Optional dev environment — activated automatically by direnv

# This makes `runt` resolve to the local debug build (bin/runt wrapper)
# instead of the system-wide /usr/local/bin/runt install.
# Same with `notebook` and `runtimed`.
# xtask commands also derive the worktree path themselves, so direnv is a
# convenience for interactive shells rather than a requirement for daemon
# isolation.

# Local cargo defaults kick in: CARGO_INCREMENTAL=1 + no RUSTC_WRAPPER.
# Tight edit-check loops on one crate reuse rustc's per-function
# incremental artifacts and run in seconds. sccache is still useful
# for CI (fresh target dir every run) but its "can't cache incremental"
# constraint makes it a net loss locally when the incremental cache is
# already warm. Set RUSTC_WRAPPER=sccache yourself if you want it.
