Enum CancellationLevel 

pub enum CancellationLevel {
    None,
    BestEffortRequest,
    ExactRequest,
    RangeSubset,
}

Cancellation precision supported by an operation boundary.

Variants

None

Cancellation is not propagated.

BestEffortRequest

Cancellation is advisory and may race with completion.

ExactRequest

One complete request can be cancelled precisely.

RangeSubset

A subset of one range request can be cancelled while other ranges continue.

Implementations

impl CancellationLevel

pub fn intersection(self, other: Self) -> Self

Returns the strongest cancellation level guaranteed by both sides.

Trait Implementations

impl Clone for CancellationLevel

fn clone(&self) -> CancellationLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CancellationLevel

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

Formats the value using the given formatter.

impl Default for CancellationLevel

fn default() -> CancellationLevel

Returns the “default value” for a type.

impl Ord for CancellationLevel

fn cmp(&self, other: &CancellationLevel) -> 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 CancellationLevel

fn eq(&self, other: &CancellationLevel) -> 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 CancellationLevel

fn partial_cmp(&self, other: &CancellationLevel) -> 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.
