Trait MapImmutable

pub trait MapImmutable<'a, R: RawMutex, T: ?Sized> {
    // Required method
    fn map_immutable<U: ?Sized, F>(
        s: Self,
        f: F,
    ) -> ImmutableMappedMutexGuard<'a, R, U>
       where F: FnOnce(&T) -> &U;
}

Required Methods

fn map_immutable<U: ?Sized, F>( s: Self, f: F, ) -> ImmutableMappedMutexGuard<'a, R, U>

where F: FnOnce(&T) -> &U,

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.
