Struct TcDuration 

pub struct TcDuration {
    pub frames: u64,
    pub fps: u8,
}

A duration expressed in timecode frames.

Unlike Timecode this is not anchored to a time-of-day and can exceed 24 hours.

Fields

frames: u64

Total frames in this duration.

fps: u8

Frames per second (rounded integer).

Implementations

impl TcDuration

pub fn from_frames(frames: u64, fps: u8) -> Self

Create a duration from a frame count at a given fps.

pub fn from_hmsf( hours: u32, minutes: u32, seconds: u32, frames: u32, fps: u8, ) -> Self

Create a duration from hours, minutes, seconds, and frames.

pub fn to_hmsf(&self) -> (u32, u32, u32, u32)

Convert to (hours, minutes, seconds, frames) tuple.

pub fn as_seconds(&self) -> f64

Duration in seconds (floating point).

pub fn multiply(&self, factor: u64) -> Self

Multiply the duration by an integer factor.

pub fn divide(&self, divisor: u64) -> Option<Self>

Divide the duration by an integer divisor. Returns None if divisor is zero.

pub fn scale(&self, factor: f64) -> Self

Scale the duration by a floating-point factor (e.g. speed change).

pub fn midpoint(&self) -> Self

Compute the midpoint between zero and this duration.

pub fn add(&self, other: &TcDuration) -> Self

Add two durations together.

pub fn subtract(&self, other: &TcDuration) -> Self

Subtract another duration (saturating at zero).

pub fn is_zero(&self) -> bool

Return true if the duration is zero.

Trait Implementations

impl Clone for TcDuration

fn clone(&self) -> TcDuration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TcDuration

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

Formats the value using the given formatter.

impl Display for TcDuration

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

Formats the value using the given formatter.

impl Ord for TcDuration

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

fn eq(&self, other: &TcDuration) -> 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 PartialOrd for TcDuration

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