Struct HeapCounts 

#[non_exhaustive]
pub struct HeapCounts {
    pub live_bytes: u64,
    pub peak_bytes: u64,
    pub allocs: u32,
}

The heap’s counts at a frame’s end, in bytes asked for (never the allocator’s own overhead). Build it with HeapCounts::new (ADR-0039).

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.

live_bytes: u64

The bytes allocated and not yet freed.

peak_bytes: u64

The most bytes live at once since the program started.

allocs: u32

The calls that allocated or reallocated since the last reading: one reading a frame, so the frame’s.

Implementations

impl HeapCounts

pub const fn new(live_bytes: u64, peak_bytes: u64, allocs: u32) -> Self

live_bytes live, peak_bytes at the most, and allocs calls since the last reading.

Trait Implementations

impl Clone for HeapCounts

fn clone(&self) -> HeapCounts

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HeapCounts

impl Debug for HeapCounts

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

Formats the value using the given formatter.

impl Default for HeapCounts

fn default() -> HeapCounts

Returns the “default value” for a type.

impl JsonSchema for HeapCounts

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.
