Unified memory event type

This structure captures all essential information about memory operations across all tracking backends (core, lockfree, async, unified).

Fields

timestamp: u64

Event timestamp (nanoseconds since epoch)

event_type: MemoryEventType

ptr: usize

Memory pointer address

size: usize

Allocation size in bytes

old_size: Option<usize>

Previous allocation size (for Reallocate events)

thread_id: u64

Thread identifier

var_name: Option<String>

Optional variable name

type_name: Option<String>

Optional type name

call_stack_hash: Option<u64>

Optional call stack hash

thread_name: Option<String>

Optional thread name

source_file: Option<String>

Optional source file path

source_line: Option<u32>

Optional source line number

Implementations

impl MemoryEvent

pub fn allocate(ptr: usize, size: usize, thread_id: u64) -> Self
