Enum Color 

pub enum Color {
    White0,
    White1,
    Gray,
    Black,
}

A traced color in the tri-color invariant.

Variants

White0

Not yet visited in the current cycle. The collector alternates between two white bits so allocations made during sweep are not collected by the cycle already in progress.

White1

Alternate white bit.

Gray

Visited; outgoing references not yet traced.

Black

Fully traced; no outgoing pointers to white objects.

Implementations

impl Color

pub fn is_white(self) -> bool

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl PartialEq for Color

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

impl Copy for Color

impl Eq for Color

impl StructuralPartialEq for Color
