Required Associated Constants

const FRACTIONAL_BITS: u8

const MAX_EXPONENT: u8

const SWEET: Self

const F10: &'static [Self]

const IF10: &'static [Self]

Required Associated Types

type ALPInt: PrimInt + Display + ToPrimitive + Copy + NativePType + Into<PValue>

Required Methods

fn as_int(self) -> Self::ALPInt

Equivalent to calling as to cast the primitive float to the target integer type.

fn from_int(n: Self::ALPInt) -> Self

Convert from the integer type back to the float type using as.

Provided Methods

fn fast_round(self) -> Self

Round to the nearest floating integer by shifting in and out of the low precision range.

fn find_best_exponents(values: &[Self]) -> Exponents

fn estimate_encoded_size(encoded: &[Self::ALPInt], patches: &[Self]) -> usize

fn encode( values: &[Self], exponents: Option<Exponents>, ) -> (Exponents, Buffer<Self::ALPInt>, Buffer<u64>, Buffer<Self>, BufferMut<u64>)

fn encode_single(value: Self, exponents: Exponents) -> Option<Self::ALPInt>

fn encode_above(value: Self, exponents: Exponents) -> Self::ALPInt

fn encode_below(value: Self, exponents: Exponents) -> Self::ALPInt

fn decode(encoded: &[Self::ALPInt], exponents: Exponents) -> Vec<Self>

fn decode_buffer( encoded: BufferMut<Self::ALPInt>, exponents: Exponents, ) -> BufferMut<Self>

fn decode_into( encoded: &[Self::ALPInt], exponents: Exponents, output: &mut [Self], )

fn decode_slice_inplace(encoded: &mut [Self::ALPInt], exponents: Exponents)

fn decode_single(encoded: Self::ALPInt, exponents: Exponents) -> Self

fn encode_single_unchecked(value: Self, exponents: Exponents) -> Self::ALPInt

Encode single float value. The returned value might decode to a different value than passed in. Consider using Self::encode_single if you want the checked version of this function.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
