Enum DecimalMantissa 

pub enum DecimalMantissa<'a> {
    I64(i64),
    Big(Cow<'a, [u8]>),
}

Decimal mantissa representation.

Most decimals fit in i64; larger values use big-endian two’s complement bytes.

Variants

I64(i64)

Mantissa fits in signed 64-bit integer.

Big(Cow<'a, [u8]>)

Arbitrary precision: big-endian two’s complement, minimal-length.

Implementations

impl DecimalMantissa<'_>

pub fn has_trailing_zeros(&self) -> bool

Returns whether this mantissa has trailing zeros (not normalized).

pub fn is_zero(&self) -> bool

Returns true if this is the zero mantissa.

Trait Implementations

impl<'a> Clone for DecimalMantissa<'a>

fn clone(&self) -> DecimalMantissa<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for DecimalMantissa<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for DecimalMantissa<'a>

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> PartialEq for DecimalMantissa<'a>

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