Struct Hash64

pub struct Hash64 {
    pub(crate) inner: u64,
}

A u64 but encoded with a fixed size; for hashes this encoding is more compact than u64.

Fields

inner: u64

Implementations

impl Hash64

pub const ZERO: Hash64

pub fn new(n: u64) -> Self

pub fn as_u64(self) -> u64

pub fn wrapping_add(self, other: Self) -> Self

Trait Implementations

impl BitXorAssign<u64> for Hash64

fn bitxor_assign(&mut self, rhs: u64)

Performs the ^= operation.

impl Clone for Hash64

fn clone(&self) -> Hash64

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Hash64

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

Formats the value using the given formatter.

impl Default for Hash64

fn default() -> Hash64

Returns the “default value” for a type.

impl FromStableHash for Hash64

type Hash = SipHasher128Hash

fn from(StableHasherHash: Self::Hash) -> Self

Convert the finalized state of a StableHasher and construct an Self containing the processed hash.

impl Hash for Hash64

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LowerHex for Hash64

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

Formats the value using the given formatter.

impl Ord for Hash64

fn cmp(&self, other: &Hash64) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Hash64

fn eq(&self, other: &Hash64) -> 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 PartialOrd for Hash64

fn partial_cmp(&self, other: &Hash64) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
