Struct ImageSequenceDescriptor 

pub struct ImageSequenceDescriptor { /* private fields */ }

A compact description of one regular or sparse image sequence.

Implementations

impl ImageSequenceDescriptor

pub fn new( resource_id: ResourceId, pattern: ImageSequencePattern, frames: FrameRange, rate: RationalRate, known_missing_frames: Vec<i64>, ) -> Result<Self>

Creates a sequence descriptor and canonicalizes its sparse exceptions.

Errors

Returns ErrorKind::InvalidArgument when there are too many missing frames or an exception does not belong to the regular frame domain.

pub const fn resource_id(&self) -> ResourceId

Returns the compact patterned resource identity.

pub const fn pattern(&self) -> &ImageSequencePattern

Returns the sequence filename pattern.

pub const fn frames(&self) -> FrameRange

Returns the regular frame domain before sparse exceptions.

pub const fn rate(&self) -> RationalRate

Returns the exact playback or capture rate.

pub fn known_missing_frames(&self) -> &[i64]

Returns sorted, unique frames known to be absent.

pub fn is_known_missing(&self, frame: i64) -> bool

Returns whether a frame is recorded as missing.

Trait Implementations

impl Clone for ImageSequenceDescriptor

fn clone(&self) -> ImageSequenceDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageSequenceDescriptor

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

Formats the value using the given formatter.

impl Eq for ImageSequenceDescriptor

impl PartialEq for ImageSequenceDescriptor

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