Detailed allocation event for tracing

Fields

id: u64

Unique allocation ID

timestamp: Instant

Timestamp when allocated

requested_size: usize

Requested size in bytes

allocated_size: usize

Actual allocated size in bytes (may be larger due to alignment)

alignment: usize

Allocation alignment requirement

source: Option<String>

Stack trace or allocation source (for debugging)

device_id: usize

Device ID where allocated

pool_id: Option<usize>

Pool ID within device

is_active: bool

Whether this is still active

deallocated_at: Option<Instant>

When deallocated (if applicable)

lifetime_us: Option<u64>

Lifetime in microseconds (if deallocated)

Implementations

pub fn mark_deallocated(&mut self)

Mark allocation as deallocated

pub fn lifetime(&self) -> Option<Duration>

Get lifetime duration
