Trait ApplyOnce

pub trait ApplyOnce<T> {
    type Cont<_T>;

    // Required method
    fn apply_once<U, F>(self, rhs: F) -> Self::Cont<U>
       where F: FnOnce(T) -> U;
}

A the ApplyOnce trait is similar to [Map], but it consumes the instance instead of borrowing it;

Required Associated Types

type Cont<_T>

Required Methods

fn apply_once<U, F>(self, rhs: F) -> Self::Cont<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.
