Trait MapRef 

pub trait MapRef<T, E> {
    // Required method
    fn map_ref<U, F>(self, op: F) -> Result<U, E>
       where F: FnOnce(&T) -> U;
}

Required Methods

fn map_ref<U, F>(self, op: F) -> Result<U, E>

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.
