Implementations

impl Tag

pub(crate) const EMPTY: Tag = _

Control tag value for an empty bucket.

pub(crate) const DELETED: Tag = _

Control tag value for a deleted bucket.

pub(crate) const fn is_full(self) -> bool

Checks whether a control tag represents a full bucket (top bit is clear).

pub(crate) const fn is_special(self) -> bool

Checks whether a control tag represents a special value (top bit is set).

pub(crate) const fn special_is_empty(self) -> bool

Checks whether a special control value is EMPTY (just check 1 bit).

pub(crate) const fn full(hash: u64) -> Tag

Creates a control tag representing a full bucket with the given hash.

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl PartialEq for Tag

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