Expand description

Trait for implementing allocation hooks in a tracing allocator.

§Safety

Implementors must ensure that hook methods do not allocate memory (to avoid infinite recursion) and are safe to call from any thread at any time during allocation operations.

Required Methods§

Source

fn on_alloc(&self, pointer: *mut u8, size: usize, align: usize)

Source

fn on_dealloc(&self, pointer: *mut u8, size: usize, align: usize)

Source

fn on_alloc_zeroed(&self, pointer: *mut u8, size: usize, align: usize)

Source

fn on_realloc( &self, old_pointer: *mut u8, new_pointer: *mut u8, old_size: usize, new_size: usize, align: usize, )

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
