Struct HashF64

pub struct HashF64(/* private fields */);

This is a f64 wrapper suitable for use as a key in a (Hash)Map, since NaNs compare equal to each other, so it can implement Eq and Hash. HashF64(-0.0) == HashF64(0.0).

Trait Implementations

impl Clone for HashF64

fn clone(&self) -> HashF64

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HashF64

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

Formats the value using the given formatter.

impl Hash for HashF64

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 PartialEq for HashF64

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