Struct CTWritingDirection

#[repr(transparent)]
pub struct CTWritingDirection(pub i8);

Available on crate feature CTParagraphStyle only.

These constants specify the writing direction

The writing direction is algorithmically determined using the Unicode Bidirectional Algorithm rules P2 and P3.

The writing direction is left to right.

The writing direction is right to left.

Trait Implementations

impl Clone for CTWritingDirection

fn clone(&self) -> CTWritingDirection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CTWritingDirection

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

Formats the value using the given formatter.

impl Encode for CTWritingDirection

Available on crate feature objc2 only.

const ENCODING: Encoding = i8::ENCODING

The Objective-C type-encoding for this type.

impl Hash for CTWritingDirection

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 CTWritingDirection

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

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

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

impl RefEncode for CTWritingDirection

Available on crate feature objc2 only.

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.
