Struct Cancel 

pub struct Cancel(/* private fields */);

A type-erased cancel token.

Implementations

impl Cancel

pub fn cancels<T: OpCode>(&self, key: &Key<T>) -> bool

Check if this cancel token cancels the given key.

Trait Implementations

impl Clone for Cancel

fn clone(&self) -> Cancel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cancel

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

Formats the value using the given formatter.

impl Hash for Cancel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Cancel

fn eq(&self, other: &Cancel) -> 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.
