Struct CompletionToken

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

Token for listening for responses to requests

These tokens are always guaranteed, to have at most one equal counterpart, and they are deliberately not Cloneable or Copyable to help enforce that constraint.

Internally, the token contains a u64 sourced from an incrementing atomic, no guarantees are made about iteration order, and the tokens have no meaning across executions.

Implementations

impl CompletionToken

pub fn new() -> (CompletionToken, CompletionToken)

Creates a pair of equal CompletionTokens

It is guaranteed that no previous or future pair of CompletionTokens, at least within a single execution of the program, will be equal to these tokens

pub fn count(&self) -> usize

Returns the number of copies of this CompletionToken currently alive

This is used for doing “Garbage Collection” of token’s whose partners have been dropped.

Trait Implementations

impl Debug for CompletionToken

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

Formats the value using the given formatter.

impl Hash for CompletionToken

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 Ord for CompletionToken

fn cmp(&self, other: &CompletionToken) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CompletionToken

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

impl PartialOrd for CompletionToken

fn partial_cmp(&self, other: &CompletionToken) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
