Struct Alloc 

pub struct Alloc;

Available on crate feature dhat-compat only.

Drop-in replacement for dhat::Alloc.

Unit struct usable in the literal static A: Alloc = Alloc; pattern that dhat-rs documents. Internally forwards every allocation to a process-wide static crate::ModAlloc so HeapStats::get() and Profiler find the live counters.

Example

use mod_alloc::dhat_compat::Alloc;

#[global_allocator]
static ALLOC: Alloc = Alloc;

Implementations

impl Alloc

pub const fn new() -> Self

Construct an Alloc value (also usable as just Alloc).

Provided for parity with ModAlloc::new() and for downstream code that prefers the constructor form. The preferred dhat-style pattern is static A: Alloc = Alloc;.

Trait Implementations

impl Default for Alloc

fn default() -> Self

Returns the “default value” for a type.

impl GlobalAlloc for Alloc

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

Allocates memory as described by 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 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.
