Enum Rounding 

pub enum Rounding {
    Trunc,
    Ceil,
    HalfEven,
    HalfUp,
}

How to round when rendering an exact internal value into a coarser form.

Rule R: rounding exists only when rendering. No API that constructs absolute time may round — construction from a foreign unit is exact or it is UCAL-E0043.

Variants

Trunc

Toward the datum.

Ceil

Away from the datum.

HalfEven

Nearest, ties to even. The default, and the mode §2.2 uses for the datum.

HalfUp

Nearest, ties away from the datum.

Trait Implementations

impl Clone for Rounding

fn clone(&self) -> Rounding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Rounding

impl Debug for Rounding

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

Formats the value using the given formatter.

impl Default for Rounding

fn default() -> Rounding

Returns the “default value” for a type.

impl Eq for Rounding

impl Hash for Rounding

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 Ord for Rounding

fn cmp(&self, other: &Rounding) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Rounding

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Rounding

fn partial_cmp(&self, other: &Rounding) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
