Enum RoundingMode 

pub enum RoundingMode {
    Down,
    Up,
    TowardZero,
    AwayFromZero,
    HalfEven,
    HalfUp,
    HalfDown,
}

Rounding mode for decimal operations.

Variants

Down

Round toward negative infinity.

Up

Round toward positive infinity.

TowardZero

Round toward zero (truncate).

AwayFromZero

Round away from zero.

HalfEven

Round to nearest, ties go to even (banker’s rounding).

HalfUp

Round to nearest, ties round up.

HalfDown

Round to nearest, ties round down.

Trait Implementations

impl Clone for RoundingMode

fn clone(&self) -> RoundingMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoundingMode

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

Formats the value using the given formatter.

impl Default for RoundingMode

fn default() -> RoundingMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RoundingMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for RoundingMode

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 PartialEq for RoundingMode

fn eq(&self, other: &RoundingMode) -> 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 Serialize for RoundingMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RoundingMode

impl Eq for RoundingMode

impl StructuralPartialEq for RoundingMode
