Struct ArenaStats 

pub struct ArenaStats {
    pub len: usize,
    pub capacity: usize,
}

Statistics about an arena’s memory usage.

Fields

len: usize

Number of allocated values.

capacity: usize

Current capacity (number of values that fit without reallocation).

Implementations

impl ArenaStats

pub fn utilisation(&self) -> f64

Fraction of capacity used (0.0 to 1.0).

pub fn free(&self) -> usize

Number of free slots remaining before reallocation.

Trait Implementations

impl Clone for ArenaStats

fn clone(&self) -> ArenaStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArenaStats

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

Formats the value using the given formatter.

impl Display for ArenaStats

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

Formats the value using the given formatter.

impl PartialEq for ArenaStats

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