Enum JoinPolicy 

#[non_exhaustive]
pub enum JoinPolicy {
    All,
    AllSettled,
    First,
}

How spawned work is recombined.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

All

Wait for all; a failure fails the join.

AllSettled

Wait for all, keeping whatever succeeded.

First

Take the first success and cancel the rest.

Implementations

impl JoinPolicy

pub fn label(&self) -> &'static str

A label for telemetry, in the spirit of Effect::label.

Trait Implementations

impl Clone for JoinPolicy

fn clone(&self) -> JoinPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinPolicy

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

Formats the value using the given formatter.

impl Default for JoinPolicy

fn default() -> JoinPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for JoinPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for JoinPolicy

fn eq(&self, other: &JoinPolicy) -> 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 Serialize for JoinPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
