Struct bonsaidb::core::transmog_pot::pot::format::Float

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

A floating point number that can safely convert between other number types using compile-time evaluation when possible.

Implementations

impl Float

pub fn is_zero(&self) -> bool

Returns true if the value contained is zero.

pub fn as_f32(&self) -> Result<f32, Error>

Returns this number as an f32, if it can be done without losing precision.

pub const fn as_f64(&self) -> f64

Returns this number as an f64.

pub fn as_integer(&self) -> Result<Integer, Error>

Returns this number as an Integer, if the stored value has no fractional part.

pub fn write_to<W>(&self, writer: W) -> Result<usize, Error>

where W: WriteBytesExt,

Writes this value using the smallest form possible.

pub fn read_from<R>( kind: Kind, byte_len: usize, reader: &mut R ) -> Result<Float, Error>

where R: ReadBytesExt,

Reads a floating point number given the atom kind and byte_len. byte_len should be the exact argument from the atom header.

Trait Implementations

impl Clone for Float

fn clone(&self) -> Float

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Float

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

Formats the value using the given formatter.

impl Display for Float

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

Formats the value using the given formatter.

impl From<f32> for Float

fn from(value: f32) -> Float

Converts to this type from the input type.

impl From<f64> for Float

fn from(value: f64) -> Float

Converts to this type from the input type.

impl PartialEq for Float

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
