Struct HotPathDetectingAlloc 

pub struct HotPathDetectingAlloc { /* private fields */ }

Global allocator that detects hot path allocations.

When the allocation-tracking feature is enabled and hot path detection is active for a thread, this allocator will panic on any heap allocation.

Example

To enable this allocator in your binary:

use laminar_core::alloc::HotPathDetectingAlloc;

#[global_allocator]
static ALLOC: HotPathDetectingAlloc = HotPathDetectingAlloc::new();

Implementations

impl HotPathDetectingAlloc

pub const fn new() -> Self

Create a new hot path detecting allocator.

Trait Implementations

impl Default for HotPathDetectingAlloc

Available on crate feature allocation-tracking only.

fn default() -> Self

Returns the “default value” for a type.

impl GlobalAlloc for HotPathDetectingAlloc

Available on crate feature allocation-tracking only.

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

Allocates memory as described by the given layout.

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

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

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

Shrinks or grows a block of memory to the given new_size in bytes. The block is described by the given ptr pointer and 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.
