Trait Implementations

impl<C: Clone, E: Clone, V: Clone> Clone for Promise<C, E, V>

fn clone(&self) -> Promise<C, E, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<C: Debug, E: Debug, V: Debug> Debug for Promise<C, E, V>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<C: PartialEq, E: PartialEq, V: PartialEq> PartialEq<Promise<C, E, V>> for Promise<C, E, V>

fn eq(&self, other: &Promise<C, E, V>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Promise<C, E, V>) -> bool

This method tests for !=.
