Expand description

Memory allocation stats gathered during the lifetime of the allocator.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§bytes_allocated: u32

The current number of bytes allocated.

This represents how many bytes are allocated right now.

§bytes_allocated_peak: u32

The peak number of bytes ever allocated.

This is the maximum the bytes_allocated ever reached.

§bytes_allocated_sum: u128

The sum of every allocation ever made.

This increases every time a new allocation is made.

§address_space_used: u32

The amount of address space (in bytes) used by the allocator.

This is calculated as the difference between the allocator’s bumper and the heap base.

Currently the bumper’s only ever incremented, so this is simultaneously the current value as well as the peak value.
