Struct AVCaptionRegionDisplayAlignment 

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

Available on crate feature AVCaption only.

Choices for region display alignment

Whenever a caption line is inserted into a region, it’s placed relative to the existing lines and the direction to which the line is placed is called the block progression direction of the region. For example, English caption’s block progression direction is top-to-bottom, while Japanese vertical caption uses right-to-left.

The value describes how the caption lines should positioned in a region in terms of the block progression direction.

Align lines in earlier position in the block progression direction, or align to the top for English captions, for example.

Align lines in center position in the block progression direction. iTT doesn’t support this.

Align lines in later position in the block progression direction, or align to the left for Japanese vertical captions, for example.

impl Ord for AVCaptionRegionDisplayAlignment

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

impl PartialEq for AVCaptionRegionDisplayAlignment

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

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