Struct CapturePool 

pub struct CapturePool { /* private fields */ }

A dedicated memory pool for CUDA graph capture.

During graph capture, allocations must come from a pool that is not sealed. Once sealed, the pool rejects new allocations — this is used to ensure that all buffers are pre-allocated before capture begins.

Usage

let pool = CapturePool::new();
// ... allocate buffers from pool ...
pool.seal();  // no more allocations allowed

// begin_capture_with_pool(&pool, stream) would fail here because
// the pool is sealed — you can't allocate during capture from a
// sealed pool. Un-seal it first or use a fresh pool.

Implementations

impl CapturePool

pub fn new() -> Self

Create a new, unsealed capture pool.

pub fn seal(&self)

Seal the pool, preventing any further allocations.

pub fn unseal(&self)

Unseal the pool, allowing allocations again.

pub fn is_capture_pool_sealed(&self) -> bool

Check whether the pool is sealed.

Trait Implementations

impl Default for CapturePool

Available on crate feature cuda only.

fn default() -> Self

Returns the “default value” for a type.
