Trait WithInner

pub trait WithInner<O> {
    // Required methods
    fn with_inner<F, R>(&'static self, f: F) -> Option<R>
       where F: FnOnce(&O) -> R;
    fn with_inner_mut<F, R>(&'static self, f: F) -> Option<R>
       where F: FnOnce(&mut O) -> R;
}

Required Methods

fn with_inner<F, R>(&'static self, f: F) -> Option<R>

where F: FnOnce(&O) -> R,

fn with_inner_mut<F, R>(&'static self, f: F) -> Option<R>

where F: FnOnce(&mut O) -> R,

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.
