Trait Implementations

impl Clone for ChachaControl

fn clone(&self) -> ChachaControl

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for ChachaControl

fn default() -> ChachaControl

Returns the “default value” for a type.

impl PartialEq for ChachaControl

fn eq(&self, other: &ChachaControl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
