Enum RoundMode 

pub enum RoundMode {
    Floor,
    Ceil,
    Truncate,
    HalfUp,
    HalfDown,
    HalfEven,
    Fract,
}

Rounding modes for decimal operations.

Variants

Floor

Round toward negative infinity.

Ceil

Round toward positive infinity.

Truncate

Round toward zero (truncate).

HalfUp

Round half away from zero (>= 0.5 rounds up).

HalfDown

Round half toward zero (> 0.5 rounds up).

HalfEven

Banker’s rounding: half rounds to nearest even.

Fract

Return the fractional part only.

Trait Implementations

impl Clone for RoundMode

fn clone(&self) -> RoundMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoundMode

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

Formats the value using the given formatter.

impl PartialEq for RoundMode

fn eq(&self, other: &RoundMode) -> 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.

impl Copy for RoundMode
