Enum Decimal 

pub enum Decimal {
    NaN,
    Infinity {
        negative: bool,
    },
    Finite {
        negative: bool,
        coefficient: u128,
        exponent: i32,
    },
}

A 128-bit decimal (IEEE 754-2008 decimal128), as Java’s org.bson.types.Decimal128 reads and prints it.

Variants

NaN

Infinity

Fields

negative: bool

Finite

coefficient × 10^exponent, the coefficient at most 34 digits.

Fields

negative: bool

coefficient: u128

exponent: i32

Implementations

impl Decimal

pub fn parse(text: &str) -> Option<Self>

Reads a decimal as Decimal128.parse does: NaN, Infinity (or Inf, either signed, any case), or a decimal (-1.2e3), held exactly in 34 digits once trailing zeros are dropped and the exponent clamped; None otherwise (“Invalid decimal128 string”).

Trait Implementations

impl Clone for Decimal

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Decimal

impl Debug for Decimal

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

Formats the value using the given formatter.

impl Display for Decimal

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

Decimal128.toString(): plain notation for an exponent at most 0 and an adjusted exponent at least -6, else scientific (-1.2E+3).

impl Eq for Decimal

impl PartialEq for Decimal

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

Equality operator ==.

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

Inequality operator !=.
