Struct TcDuration 

pub struct TcDuration {
    pub frames: i64,
    pub frame_rate_num: u32,
    pub frame_rate_den: u32,
}

A duration expressed as a frame count at a given frame rate

Fields

frames: i64

Signed frame count (negative = before reference point)

frame_rate_num: u32

Frame rate numerator

frame_rate_den: u32

Frame rate denominator

Implementations

impl TcDuration

pub fn new(frames: i64, frame_rate_num: u32, frame_rate_den: u32) -> Self

Create a new TcDuration

pub fn to_seconds(&self) -> f64

Convert to floating-point seconds

pub fn to_milliseconds(&self) -> f64

Convert to milliseconds

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

Add two durations (must share the same frame rate)

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

Subtract other from self. Returns None if the result would be negative.

pub fn is_negative(&self) -> bool

Returns true when the frame count is negative

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 Copy for TcDuration

impl Debug for TcDuration

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

Formats the value using the given formatter.

impl Eq for TcDuration

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.
