Hook trait for intercepting trait declaration analysis.

Provided Methods

fn on_enter_trait( &self, _trait_: &Trait<'_>, _metadata: &ClassLikeMetadata, _context: &mut HookContext<'_, '_>, ) -> HookResult<()>

Called when entering a trait declaration.

Errors

Returns [HookError] if the underlying plugin implementation propagates one.

fn on_leave_trait( &self, _trait_: &Trait<'_>, _metadata: &ClassLikeMetadata, _context: &mut HookContext<'_, '_>, ) -> HookResult<()>

Called when leaving a trait declaration.

Errors

Returns [HookError] if the underlying plugin implementation propagates one.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
