Struct tracing_allocations::TracingAllocator

#[non_exhaustive]
pub struct TracingAllocator<A> {
    pub allocator: A,
}

An allocator that emits tracing events.

Usage

use std::alloc::System;
use tracing_allocations::TracingAllocator;

#[global_allocator]
static ALLOCATOR: TracingAllocator<System> = TracingAllocator::new(System);

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

allocator: A

Implementations

impl<A> TracingAllocator<A>

pub const fn new(allocator: A) -> Self

Constructs a tracing allocator.

Usage

use std::alloc::System;
use tracing_allocations::TracingAllocator;

#[global_allocator]
static ALLOCATOR: TracingAllocator<System> = TracingAllocator::new(System);

Trait Implementations

impl<A> GlobalAlloc for TracingAllocator<A> where
    A: GlobalAlloc, 

unsafe fn alloc(&self, layout: Layout) -> *mut u8

Allocate memory as described by the given layout.

unsafe fn dealloc(&self, ptr: *mut u8, layout: Layout)

Deallocate the block of memory at the given ptr pointer with the given layout.

unsafe fn alloc_zeroed(&self, layout: Layout) -> *mut u8

Behaves like alloc, but also ensures that the contents are set to zero before being returned.

unsafe fn realloc(
    &self,
    ptr: *mut u8,
    layout: Layout,
    new_size: usize
) -> *mut u8

Shrink or grow a block of memory to the given new_size. The block is described by the given ptr pointer and layout.
