Struct cbor_data::value::Exponential

pub struct Exponential<'a, B: Base> { /* private fields */ }

A representation of a bignum

The base is statically known while the exponent is dynamic. The mantissa is not guaranteed to have optimal encoding, i.e. it can have leading zero bytes.

The represented value is m * base.pow(exponent), where

• m = mantissa for inverted == false, and
• m = -1 - mantissa for inverted = true.

Implementations

impl<'a, B: Base> Exponential<'a, B>

pub fn new(exponent: i128, mantissa: Cow<'a, [u8]>, inverted: bool) -> Self

pub fn make_static(self) -> Exponential<'static, B>

Cut ties with possibly referenced byte slices, allocating if necessary

pub fn exponent(&self) -> i128

Get a reference to the exponential’s exponent.

pub fn mantissa(&self) -> &[u8]

Get a reference to the exponential’s mantissa.

pub fn inverted(&self) -> bool

Get a reference to the exponential’s inverted.

Trait Implementations

impl<'a, B: Clone + Base> Clone for Exponential<'a, B>

fn clone(&self) -> Exponential<'a, B>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, B: Debug + Base> Debug for Exponential<'a, B>

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

Formats the value using the given formatter.

impl<'a, B: Hash + Base> Hash for Exponential<'a, B>

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<'a, B: PartialEq + Base> PartialEq<Exponential<'a, B>> for Exponential<'a, B>

fn eq(&self, other: &Exponential<'a, B>) -> 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.
