Struct FrameRange 

pub struct FrameRange { /* private fields */ }

An inclusive, regularly stepped frame domain.

Implementations

impl FrameRange

pub fn new(start: i64, end: i64, step: u32) -> Result<Self>

Creates an inclusive range whose end is aligned to its step.

Errors

Returns ErrorKind::InvalidArgument for a reversed range, zero step, or an end frame not reachable from the start by whole steps.

pub const fn start(self) -> i64

Returns the first frame number.

pub const fn end(self) -> i64

Returns the last frame number.

pub const fn step(self) -> u32

Returns the positive frame-number increment.

pub fn frame_count(self) -> u128

Returns the exact number of frames in the regular domain.

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

Returns whether the frame belongs to the stepped domain.

Trait Implementations

impl Clone for FrameRange

fn clone(&self) -> FrameRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FrameRange

impl Debug for FrameRange

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

Formats the value using the given formatter.

impl Eq for FrameRange

impl Hash for FrameRange

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 PartialEq for FrameRange

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