Minimum Supported Rust Version (MSRV) Policy

We follow these MSRV rules:

  • The current MSRV is 1.88.
  • MSRV bumps do NOT require a major release and may happen in minor releases.
  • The MSRV may be updated when needed, but support for the current stable Rust release and the previous two stable releases (N, N-1, N-2) is always guaranteed.
- For example, if the current stable version is 1.85, we guarantee support for 1.85, 1.84, and 1.83, so the minimum supported Rust version will be at most 1.83.
  • MSRV is bumped only when needed, e.g.:
- required by dependencies - any serious bug is found (including security-related) - adopting new stable Rust features
  • Every MSRV bump is documented in the release notes when it happens.

Platforms

  • Linux / Android: inotify
  • macOS: FSEvents or kqueue, see features
  • Windows: ReadDirectoryChangesW
  • iOS / FreeBSD / NetBSD / OpenBSD / DragonflyBSD: kqueue
  • All platforms: polling

Origins

Inspired by Go's [fsnotify] and Node.js's [Chokidar], born out of need for [cargo watch], and general frustration at the non-existence of C/Rust cross-platform notify libraries.
