Struct StreamInstant 

pub struct StreamInstant(pub u64);

Represents a point in stream time, anchored to estimated playback position.

StreamInstant represents the estimated playback time of points, not merely “points sent so far.” When used in ChunkRequest::start, it represents:

start = playhead + buffered

Where:

• playhead = stream_epoch + estimated_consumed_points
• buffered = points sent but not yet played

This allows callbacks to generate content for the exact time it will be displayed, enabling accurate audio synchronization.

Implementations

impl StreamInstant

pub fn new(points: u64) -> Self

Create a new stream instant from a point count.

pub fn points(&self) -> u64

Returns the number of points since stream start.

pub fn as_seconds(&self, pps: u32) -> f64

Convert this instant to seconds at the given points-per-second rate.

pub fn as_secs_f64(&self, pps: u32) -> f64

Convert to seconds at the given PPS.

This is an alias for as_seconds() for consistency with standard Rust duration naming conventions (e.g., Duration::as_secs_f64()).

pub fn from_seconds(seconds: f64, pps: u32) -> Self

Create a stream instant from a duration in seconds at the given PPS.

pub fn add_points(&self, points: u64) -> Self

Add a number of points to this instant.

pub fn sub_points(&self, points: u64) -> Self

Subtract a number of points from this instant (saturating at 0).

Trait Implementations

impl Add<u64> for StreamInstant

type Output = StreamInstant

The resulting type after applying the + operator.

fn add(self, rhs: u64) -> Self::Output

Performs the + operation.

impl AddAssign<u64> for StreamInstant

fn add_assign(&mut self, rhs: u64)

Performs the += operation.

impl Clone for StreamInstant

fn clone(&self) -> StreamInstant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamInstant

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

Formats the value using the given formatter.

impl Default for StreamInstant

fn default() -> StreamInstant

Returns the “default value” for a type.

impl Hash for StreamInstant

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 StreamInstant

fn cmp(&self, other: &StreamInstant) -> 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,

impl PartialEq for StreamInstant

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

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

fn sub(self, rhs: u64) -> Self::Output

Performs the - operation.

impl SubAssign<u64> for StreamInstant

fn sub_assign(&mut self, rhs: u64)

Performs the -= operation.
