Enum JoinKind 

pub enum JoinKind {
    All = 0,
    Race = 1,
    Any = 2,
    Settle = 3,
}

Join strategy for async join expressions

Variants

All = 0

Wait for all branches to complete, return tuple of results

Race = 1

Return the first branch to complete, cancel the rest

Any = 2

Return the first branch to succeed (non-error), cancel the rest

Settle = 3

Wait for all branches, preserve individual success/error results

Trait Implementations

impl Clone for JoinKind

fn clone(&self) -> JoinKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JoinKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for JoinKind

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
