Manage Rust API stability with semantic versioning in Cargo.toml and the #[deprecated] attribute to warn users of changes without breaking builds.
Manage API stability in Rust by using semantic versioning in Cargo.toml and marking deprecated items with the #[deprecated] attribute to warn users without breaking compilation.
#[deprecated(since = "1.0.0", note = "Use `new_function` instead")]

Rust’s compiler enforces stability by refusing to compile code that violates ownership rules, ensuring that refactoring and feature additions do not introduce subtle bugs.
Rust keeps your API stable by using version numbers to track changes and warning labels to tell users when old code is being replaced. This is like a library updating its book catalog: it keeps old titles listed but marks them as 'out of print' so readers know to look for the new edition. You use this to update your software safely without breaking existing projects.
