Enum JoinMode 

pub enum JoinMode {
    All,
    Any,
    Race,
    AllSettled,
}

Fanout join semantics (Promise / futures combinators).

Variants

All

every branch runs; out is an array of per-branch final ctx (Promise.all / futures::try_join_all).

Any

first non-raising branch’s ctx wins; all-fail raises (Promise.any / futures::future::select_ok).

Race

first branch to settle wins, success OR raise (Promise.race / futures::future::select).

AllSettled

every branch runs, never raises; per-item record {status: fulfilled|rejected, value|reason} (Promise.allSettled).

Trait Implementations

impl Clone for JoinMode

fn clone(&self) -> JoinMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JoinMode

impl Debug for JoinMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JoinMode

fn deserialize<__D>( __deserializer: __D, ) -> Result<JoinMode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for JoinMode

impl PartialEq for JoinMode

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
