Crates in this directory are published to crates.io and obey semver.
They could live in a separate repo, but we want to experiment with a monorepo setup.
We use these crates from crates.io, not the local copies because we want to ensure that rust-analyzer works with the versions that are published. This means if you add a new API to these crates, you need to release a new version to crates.io before you can use that API in rust-analyzer.
To release new versions of these packages, change their version in Cargo.toml. Once your PR is merged into master a workflow will automatically publish the new version to crates.io.
While prototyping, the local versions can be used by uncommenting the relevant lines in the [patch.'crates-io'] section in Cargo.toml
