Version information trait.

All version types must implement this to work with generic handlers.

Required Methods

fn version_string(&self) -> &str

Version string (e.g., “1.0.214”, “14.21.3”).

fn is_yanked(&self) -> bool

Whether this version is yanked/deprecated.

fn as_any(&self) -> &dyn Any

Downcast to concrete version type

Provided Methods

fn is_prerelease(&self) -> bool

Whether this version is a pre-release (alpha, beta, rc, etc.).

Default implementation checks for common pre-release patterns.

fn features(&self) -> Vec<String>

Available feature flags (empty if not supported by ecosystem).

fn is_stable(&self) -> bool

Whether this version is stable (not yanked and not pre-release).
