Struct AVSampleBufferRequestDirection

#[repr(transparent)]
pub struct AVSampleBufferRequestDirection(pub NSInteger);

Available on crate feature AVSampleBufferGenerator only.

Indicates the direction in which the samples should be generated for the AVSampleBufferRequest.

Indicates only one sample will be loaded at [AVSampleBufferRequest startCursor], and the [AVSampleBufferRequest limitCursor], [AVSampleBufferRequest preferredMinSampleCount], and [AVSampleBufferRequest maxSampleCount] will be ignored.

Indicates zero or more following samples may be loaded from [AVSampleBufferRequest startCursor], subject to [AVSampleBufferRequest limitCursor], [AVSampleBufferRequest preferredMinSampleCount], and [AVSampleBufferRequest maxSampleCount]

Indicates zero or more preceeding samples may be loaded from [AVSampleBufferRequest startCursor], subject to [AVSampleBufferRequest limitCursor], [AVSampleBufferRequest preferredMinSampleCount], and [AVSampleBufferRequest maxSampleCount]

Trait Implementations

impl Clone for AVSampleBufferRequestDirection

fn clone(&self) -> AVSampleBufferRequestDirection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AVSampleBufferRequestDirection

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

Formats the value using the given formatter.

impl Encode for AVSampleBufferRequestDirection

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for AVSampleBufferRequestDirection

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 Ord for AVSampleBufferRequestDirection

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

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

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