Struct EventPoolDesc 

pub struct EventPoolDesc {
    pub capacity: u32,
    pub scope: EventScope,
    /* private fields */
}

Descriptor for a zeEventPoolCreate call.

An event pool is a fixed-capacity arena of events. The recorder hands out monotonically-increasing event indices via EventPoolDesc::alloc_event until the pool is exhausted, modelling the index bookkeeping that the device-gated zeEventCreate performs.

Fields

capacity: u32

Maximum number of events the pool can hold.

scope: EventScope

Visibility scope applied to all events.

Implementations

impl EventPoolDesc

pub fn new(capacity: u32, scope: EventScope) -> LevelZeroResult<Self>

Create a pool descriptor with capacity slots and scope visibility.

pub fn alloc_event(&mut self) -> LevelZeroResult<u32>

Reserve the next event index in the pool.

Returns LevelZeroError::OutOfMemory when the pool is exhausted.

pub fn remaining(&self) -> u32

Number of events still available in the pool.

pub fn is_host_visible(&self) -> bool

true when host-side zeEventHostSynchronize is permitted.
