# Opt-in tokio convenience: `Engine::subscribe_mem_changes_broadcast`
# wraps the Core callback API in a `tokio::sync::broadcast::Receiver`
# so axum-style consumers can consume events as a tokio stream without
# wiring the boilerplate themselves. Adds tokio (broadcast / sync only)
# to the dependency graph; consumers that don't need it keep tokio out.
tokio = ["dep:tokio"]
# Opt-in cross-process change-event surface: `watch_mem_repo` returns
# a `(handle, mpsc::Receiver<MemChangedEvent>)` pair that fires on
# every `refs/heads/<mem>` mutation in a mem-repo gitdir. Adds
# `notify` to the dependency graph; consumers that only need the
# in-process `Engine::subscribe_mem_changes` keep it out.
