Struct GcStats 

pub struct GcStats {
    pub marked: usize,
    pub collected: usize,
    pub total_before: usize,
}

Statistics returned by garbage collection.

Fields

marked: usize

Number of objects that were marked as reachable.

collected: usize

Number of objects that were collected (freed).

total_before: usize

Number of objects that existed before collection.

Implementations

impl GcStats

pub const fn did_collect(&self) -> bool

Check if any garbage was collected.

pub const fn remaining(&self) -> usize

Get the number of objects remaining after collection.

pub fn collection_ratio(&self) -> f32

Get the collection ratio (0.0 to 1.0).

Returns 0.0 if no objects existed before collection.

pub fn survival_ratio(&self) -> f32

Get the survival ratio (0.0 to 1.0).

Returns 1.0 if no objects existed before collection.

Trait Implementations

impl Clone for GcStats

fn clone(&self) -> GcStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GcStats

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

Formats the value using the given formatter.

impl Default for GcStats

fn default() -> GcStats

Returns the “default value” for a type.

impl PartialEq for GcStats

fn eq(&self, other: &GcStats) -> 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.
