Struct sc_executor_common::wasm_runtime::AllocationStats

#[non_exhaustive]
pub struct AllocationStats {
    pub bytes_allocated: u32,
    pub bytes_allocated_peak: u32,
    pub bytes_allocated_sum: u128,
    pub address_space_used: u32,
}

Memory allocation stats gathered during the lifetime of the allocator.

Fields (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.

Trait Implementations

impl Clone for AllocationStats

fn clone(&self) -> AllocationStats

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AllocationStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for AllocationStats

fn default() -> AllocationStats

Returns the “default value” for a type.
