Struct RationalTime 

pub struct RationalTime { /* private fields */ }

An exact integer value measured at a rational rate.

Implementations

impl RationalTime

pub const fn new(value: i64, rate: RationalRate) -> Self

Creates a rational time value.

pub const fn value(self) -> i64

Returns the integer value at this time’s rate.

pub const fn rate(self) -> RationalRate

Returns the rate used to interpret the value.

pub fn checked_cmp(self, other: Self) -> Result<Ordering>

Compares two time values exactly without floating-point conversion.

Errors

Returns ErrorKind::InvalidArgument if checked cross multiplication exceeds the internal comparison range.

pub fn equivalent(self, other: Self) -> Result<bool>

Returns whether two values denote the same exact time.

Errors

Returns an error under the same conditions as Self::checked_cmp.

pub fn rescaled_to(self, rate: RationalRate) -> Result<Self>

Converts this value to rate when the result is an exact integer.

Errors

Returns ErrorKind::InvalidArgument if the target rate cannot represent the time exactly or the converted value exceeds i64.

Trait Implementations

impl Clone for RationalTime

fn clone(&self) -> RationalTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RationalTime

impl Debug for RationalTime

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

Formats the value using the given formatter.

impl Display for RationalTime

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

Formats the value and normalized rate as value@numerator/denominator.

impl Eq for RationalTime

impl FromStr for RationalTime

fn from_str(value: &str) -> Result<Self>

Parses the canonical value@numerator/denominator representation.

type Err = Error

The associated error which can be returned from parsing.

impl Hash for RationalTime

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 RationalTime

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