Struct TimeBase 

pub struct TimeBase { /* private fields */ }

The clock of a framed sequence: one frame per stride samples at rate.

Kept exact as the pair rather than a frames-per-second float, so samples is integer arithmetic and two values that must share sample arithmetic can be checked for representational equality (see the module doc for why representational, not numeric).

Implementations

impl TimeBase

pub const fn new(rate: SampleRate, stride: NonZeroU32) -> Self

A latent clock ticking once per stride samples at rate.

pub const fn of_samples(rate: SampleRate) -> Self

The PCM clock itself: one frame per sample.

pub const fn sample_rate(self) -> SampleRate

The underlying sample rate.

pub const fn stride(self) -> NonZeroU32

Samples per frame.

pub fn frames_per_second(self) -> f64

Frames per second, for display and budget arithmetic. The exact value lives in the pair; this projection is lossy and never drives layout.

pub fn samples(self, frames: Frames) -> Option<Samples>

Exact sample count covered by frames, or None on u64 overflow.

pub fn frames_exact(self, samples: Samples) -> Option<Frames>

Frame count that exactly covers samples, or None if samples is not a whole number of frames. Partial frames are a caller decision (pad or reject), never a silent truncation.

pub fn seconds(self, frames: Frames) -> f64

Duration of frames in seconds.

Trait Implementations

impl Clone for TimeBase

fn clone(&self) -> TimeBase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TimeBase

impl Debug for TimeBase

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TimeBase

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TimeBase

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

Formats the value using the given formatter.

impl Eq for TimeBase

impl Hash for TimeBase

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 TimeBase

fn eq(&self, other: &TimeBase) -> 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 TimeBase

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
