Struct re_memory::accounting_allocator::AccountingAllocator

pub struct AccountingAllocator<InnerAllocator> {
    allocator: InnerAllocator,
}

Install this as the global allocator to get memory usage tracking.

Use set_tracking_callstacks or turn_on_tracking_if_env_var to turn on memory tracking. Collect the stats with tracking_stats.

Usage:

use re_memory::AccountingAllocator;

#[global_allocator]
static GLOBAL: AccountingAllocator<std::alloc::System> = AccountingAllocator::new(std::alloc::System);

Fields

allocator: InnerAllocator

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

Allocate 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)

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

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

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