Enum SyncMechanism 

#[non_exhaustive]
pub enum SyncMechanism {
    None,
    ImplicitGlFlush,
    ExplicitExternalSemaphore,
    ExplicitFence,
}

Describes how the producer signals that a frame is ready and how the consumer signals that it has finished reading.

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.

None

No synchronization is needed (e.g. single-threaded, or the producer and consumer share a submission queue).

ImplicitGlFlush

The producer calls glFlush() before handing the frame over. This is the most common mechanism for GL→wgpu interop and the default used by ImplicitOnlySynchronizer.

ExplicitExternalSemaphore

An explicit Vulkan/Metal external semaphore is signalled by the producer. Not yet handled by any built-in synchronizer.

ExplicitFence

An explicit CPU-side fence is used. Not yet handled by any built-in synchronizer.

Trait Implementations

impl Clone for SyncMechanism

fn clone(&self) -> SyncMechanism

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyncMechanism

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

Formats the value using the given formatter.

impl PartialEq for SyncMechanism

fn eq(&self, other: &SyncMechanism) -> 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.
