Enum SpawnHandleConcurrency 

pub enum SpawnHandleConcurrency {
    ImmutableShare,
    CopyOnWrite,
    SynchronizedMutation,
    Reject,
}

Declares how provider-owned GPU handles may cross async spawn boundaries.

This is a runtime/provider policy surface (not a semantic type fact) used by VM/runtime spawn handling to prevent unsynchronized device-handle races.

Variants

ImmutableShare

Provider supports immutable sharing of handle-backed values across spawned tasks.

CopyOnWrite

Provider supports copy-on-write semantics when spawned and parent tasks diverge.

SynchronizedMutation

Provider supports synchronized mutation for shared handles.

Reject

Provider rejects spawned sharing of raw handles.

Implementations

impl SpawnHandleConcurrency

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

Trait Implementations

impl Clone for SpawnHandleConcurrency

fn clone(&self) -> SpawnHandleConcurrency

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SpawnHandleConcurrency

impl Debug for SpawnHandleConcurrency

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SpawnHandleConcurrency

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SpawnHandleConcurrency

impl PartialEq for SpawnHandleConcurrency

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
