Struct StreamOrderedAllocConfig 

pub struct StreamOrderedAllocConfig {
    pub initial_pool_size: usize,
    pub max_pool_size: usize,
    pub release_threshold: usize,
    pub device: i32,
}

Configuration for a stream-ordered memory pool.

All sizes are in bytes.

Fields

initial_pool_size: usize

Initial pool size in bytes. The pool pre-reserves this amount of device memory when created.

max_pool_size: usize

Maximum pool size in bytes. 0 means unlimited — the pool will grow as needed (subject to device memory limits).

release_threshold: usize

Release threshold in bytes. When the pool is trimmed, at least this much memory is kept reserved for future allocations.

device: i32

The device ordinal to create the pool on.

Implementations

impl StreamOrderedAllocConfig

pub fn validate(&self) -> CudaResult<()>

Validate that the configuration is internally consistent.

Rules

• initial_pool_size must not exceed max_pool_size (when max_pool_size > 0).
• release_threshold must not exceed max_pool_size (when max_pool_size > 0).
• device must be non-negative.

Errors

Returns CudaError::InvalidValue if any rule is violated.

pub fn default_for_device(device: i32) -> Self

Returns a sensible default configuration for the given device.

• initial_pool_size = 0 (grow on demand)
• max_pool_size = 0 (unlimited)
• release_threshold = 0 (release everything on trim)

Trait Implementations

impl Clone for StreamOrderedAllocConfig

fn clone(&self) -> StreamOrderedAllocConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamOrderedAllocConfig

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

Formats the value using the given formatter.

impl PartialEq for StreamOrderedAllocConfig

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