Struct Float 

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

A floating-point value stored in its shortest CBOR encoding form.

Internally stores the raw bits as either f16, f32, or f64, preserving NaN payloads and the exact CBOR encoding. Two Float values are equal iff they encode to the same CBOR bytes.

Implementations

impl Float

pub const fn data_type(&self) -> DataType

Return the DataType indicating the storage width (f16, f32, or f64).

pub const fn to_f64(self) -> f64

Convert to f64 (NaN payloads are preserved).

pub const fn to_f32(self) -> Result<f32>

Convert to f32. Returns Err(Precision) for f64-width values.

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 Ord for Float

fn cmp(&self, other: &Float) -> 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.

impl PartialEq for Float

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

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.
