Struct decstr::Bitstring

impl Bitstring

pub fn try_from_le_bytes(bytes: &[u8]) -> Result<Self, Error>

Try create a decimal from the given buffer.

The buffer is assumed to be in little-endian byte-order already. This method will fail if the buffer length is not a multiple of 4 bytes, or it’s too big to fit in a Bitstring.

pub fn as_le_bytes(&self) -> &[u8] ⓘ

Get a reference to the underlying bitstring buffer.

This buffer is always stored in little-endain byte-order, regardless of the endianness of the platform.

pub fn zero() -> Self

Create a decimal with the finite value zero.

impl Bitstring

pub fn is_sign_negative(&self) -> bool

Whether or not the sign bit is set.

pub fn is_finite(&self) -> bool

Whether or not the decimal is a finite number.

pub fn is_infinite(&self) -> bool

Whether or not the decimal is an infinity.

pub fn is_nan(&self) -> bool

Whether the decimal is not a NaN.

pub fn is_quiet_nan(&self) -> bool

Whether the decimal is a qNaN.

pub fn is_signaling_nan(&self) -> bool

Whether the decimal is a sNaN.

impl Bitstring

pub fn try_parse_str(s: &str) -> Result<Bitstring, Error>

Try parse a decimal from a string.

This method is more efficient that try_parse if you already have a string to parse.

pub fn try_parse(n: impl Display) -> Result<Bitstring, Error>

Try parse a decimal from some formattable value.

This method can avoid needing to buffer an entire number upfront.
