Trait bitflags::__core::ops::FnOnce

pub trait FnOnce<Args> {
    type Output;
    extern "rust-call" fn call_once(self, args: Args) -> Self::Output;
}

A version of the call operator that takes a by-value receiver.

Associated Types

type Output

Unstable (fn_traits)

The returned type after the call operator is used.

Required Methods

extern "rust-call" fn call_once(self, args: Args) -> Self::Output

Unstable (fn_traits)

This is called when the call operator is used.
