Required Methods§

Source

fn allocate( &mut self, size: u64, alignment: u64, allocation_type: AllocationType, granularity: u64, name: &str, ) -> Result<(u64, NonZeroU64)>

Source

fn free(&mut self, chunk_id: Option<NonZeroU64>) -> Result<()>

Source

fn rename_allocation( &mut self, chunk_id: Option<NonZeroU64>, name: &str, ) -> Result<()>

Source

fn report_memory_leaks( &self, log_level: Level, memory_type_index: usize, memory_block_index: usize, )

Source

fn report_allocations(&self) -> Vec<AllocationReport>

Source

fn supports_general_allocations(&self) -> bool

Returns true if this allocator allows sub-allocating multiple allocations, false if it is designed to only represent dedicated allocations.

Source

fn allocated(&self) -> u64

Provided Methods§

Source

fn is_empty(&self) -> bool

Helper function: reports if the suballocator is empty (meaning, having no allocations).
