Implementations

impl FrameRate

pub fn as_float(&self) -> f64

Get the nominal frame rate as a float

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

Get the exact frame rate as a rational (numerator, denominator)

pub fn is_drop_frame(&self) -> bool

Check if this is a drop frame rate

pub fn drop_frames_per_minute(&self) -> u64

The number of frames dropped per discontinuity point (every non-10th minute boundary).

For 29.97 DF: 2 frames dropped per minute. For 23.976 DF: 2 frames dropped per minute (scaled from 29.97 × 24/30). For 47.952 DF: 4 frames dropped per minute (scaled from 29.97 × 48/30). For 59.94 DF: 4 frames dropped per minute (scaled from 29.97 × 60/30).

pub fn frames_per_second(&self) -> u32

Get the number of frames per second (rounded)

Trait Implementations

impl Clone for FrameRate

fn clone(&self) -> FrameRate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameRate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FrameRate

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FrameRate

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for FrameRate

impl Eq for FrameRate

impl StructuralPartialEq for FrameRate
