where Block: FnOnce(&T) -> Return,

fn with_not_null<Block>(&self, block: Block)

where Block: FnOnce(&T),

fn with_not_null_return<Block, Return>( &self, default: Return, block: Block, ) -> Return

where Block: FnOnce(&T) -> Return,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
