Struct Timescale 

pub struct Timescale(/* private fields */);

Units per second used by a track for frame timestamps.

Newtype around NonZero<u64>. Zero is structurally impossible, so the arithmetic on Timestamp can divide by self.scale without ever risking a divide by zero. Use the named constants (Self::SECOND, Self::MILLI, Self::MICRO, Self::NANO) instead of writing raw integers at call sites; for runtime values, use Self::new or TryFrom, which return TimeOverflow for 0 or for values past the QUIC varint range.

Implementations

impl Timescale

pub const SECOND: Self

One unit per second (1).

pub const MILLI: Self

1,000 units per second (1_000).

pub const MICRO: Self

1,000,000 units per second (1_000_000). Widely used by container formats; this crate’s own default is Self::MILLI.

pub const NANO: Self

1,000,000,000 units per second (1_000_000_000).

pub const fn new(units_per_second: u64) -> Result<Self, TimeOverflow>

Construct a timescale from a raw value (units per second).

Returns TimeOverflow if units_per_second is 0 (would divide by zero) or exceeds 2^62 - 1 (the QUIC varint range, matching Timestamp values). Every runtime constructor, including TryFrom, goes through this check.

pub const fn as_u64(self) -> u64

The raw units-per-second value (always non-zero).

Trait Implementations

impl Clone for Timescale

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Timescale

impl Debug for Timescale

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

Formats the value using the given formatter.

impl Default for Timescale

fn default() -> Self

Milliseconds (Self::MILLI). Every track has a timescale; this is the one used when a producer doesn’t pick one and the fallback for protocols whose wire can’t carry a timescale (pre-Lite05 moq-lite, IETF moq-transport).

impl Display for Timescale

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

Formats the value using the given formatter.

impl Eq for Timescale

impl From<Timescale> for u64

fn from(scale: Timescale) -> Self

Converts to this type from the input type.

impl From<Timescale> for NonZero<u64>

fn from(scale: Timescale) -> Self

Converts to this type from the input type.

impl Hash for Timescale

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 Timescale

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Timescale

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Timescale

fn partial_cmp(&self, other: &Self) -> 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.

impl StructuralPartialEq for Timescale

impl TryFrom<NonZero<u64>> for Timescale

fn try_from(units_per_second: NonZero<u64>) -> Result<Self, Self::Error>

Same bound as Self::new: non-zero is not enough, the value must also fit in a QUIC varint.

type Error = TimeOverflow

The type returned in the event of a conversion error.

impl TryFrom<u64> for Timescale

type Error = TimeOverflow

The type returned in the event of a conversion error.

fn try_from(units_per_second: u64) -> Result<Self, Self::Error>

Performs the conversion.
