Struct BlockId 

pub struct BlockId {
    pub ptr: u64,
    pub generation: Generation,
    pub alloc_stream: StreamId,
    pub device_ordinal: u32,
}

Compact identity of a DeviceBlock suitable for snapshotting into structures whose lifetime should not be tied to the source slice’s borrow. The fields needed to validate (ptr, generation) against the resource’s live map and to resolve alloc_stream for cross-stream waits / dealloc ordering.

Created via BlockId::from_block. Pure data; no resource handle, no Drop. Cheap to copy.

Fields

ptr: u64

generation: Generation

alloc_stream: StreamId

device_ordinal: u32

Implementations

impl BlockId

pub fn from_block(block: &DeviceBlock) -> Self

Snapshot a DeviceBlock’s identity. The returned id is independent of the original block’s borrow lifetime; the runtime’s generation guard catches stale ids whose backing allocation has been recycled.

Trait Implementations

impl Clone for BlockId

fn clone(&self) -> BlockId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockId

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

Formats the value using the given formatter.

impl PartialEq for BlockId

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