Struct interloc::InterAlloc

pub struct InterAlloc<'a, T, F> where
    T: GlobalAlloc,
    F: AllocMonitor,  {
    pub inner: T,
    pub monitor: &'a F,
}

An allocator that watches the calls to its API, sends them to a struct, and then makes the calls.

To use this struct, use the #[global_allocator] compiler directive and construct the allocator with your own custom monitor, or one of the builtins. Note that the new method of interloc::StatsMonitor is a const fn.

Fields

inner: T

Inner allocator

monitor: &'a F

Monitor on the calls to the allocator

Methods

impl<'a, T, F> InterAlloc<'a, T, F> where
    T: GlobalAlloc,
    F: AllocMonitor, 

pub fn new(base: T, monitor: &'a F) -> Self

A new instance of the allocator.

Trait Implementations

impl<'a, T, F> GlobalAlloc for InterAlloc<'a, T, F> where
    T: GlobalAlloc,
    F: AllocMonitor, 

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.
