Struct MemoryUsage

pub struct MemoryUsage {
    pub number_allocs: u64,
    pub bytes_in_use: u64,
    pub bytes_padding: u64,
    pub bytes_reserved: u64,
}

Amount of memory in use by this allocator and statistics on how much memory is reserved and wasted in total.

Fields

number_allocs: u64

The number of allocations currently active.

bytes_in_use: u64

The number of bytes that are currently actually in use.

This doesn’t include any padding or other memory that needs to be reserved, and is the minimum amount of memory that could possible be allocated.

bytes_padding: u64

The amount of bytes used for padding memory in currently active allocations.

bytes_reserved: u64

The total amount of memory reserved on the device.

This will be at least as much as bytes_in_use but in practice will be higher, as allocations reserve memory for future allocations and for padding.

Implementations

impl MemoryUsage

pub fn combine(&self, other: MemoryUsage) -> MemoryUsage

Calculate the combined memory usage of two reports (summing them).

Trait Implementations

impl Clone for MemoryUsage

fn clone(&self) -> MemoryUsage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryUsage

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

Formats the value using the given formatter.

impl Display for MemoryUsage

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

Formats the value using the given formatter.

impl PartialEq for MemoryUsage

fn eq(&self, other: &MemoryUsage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
