Struct async_alloc_counter::AsyncAllocatorCounter[−][src]

pub struct AsyncAllocatorCounter<T> {
    pub allocator: T,
}

Expand description

Allocator wrapper

this allocator will measure how much data is allocated in the future that is currently executed

Set t up as follows:

use async_alloc_counter::AsyncAllocatorCounter;
use std::{alloc::System, time::Duration};
#[global_allocator]
static GLOBAL: AsyncAllocatorCounter<System> = AsyncAllocatorCounter { allocator: System };

Fields

allocator: T

Trait Implementations

[src]

impl<T: GlobalAlloc> GlobalAlloc for AsyncAllocatorCounter<T>

[src]

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

Allocate memory as described by the given layout. Read more

[src]

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

1.28.0[src]

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. Read more

1.28.0[src]

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