Enum Direction 

#[repr(u8)]
pub enum Direction {
    Auto = 2,
    AutoRtl = 3,
    Ltr = 0,
    Rtl = 1,
}

Directionality of text

Texts may be bi-directional as specified by Unicode Technical Report #9.

Variants

Auto = 2

Auto-detect direction

The text direction is inferred from the first strongly-directional character. In case no such character is found, the text will be left-to-right.

AutoRtl = 3

Auto-detect, default right-to-left

The text direction is inferred from the first strongly-directional character. In case no such character is found, the text will be right-to-left.

Ltr = 0

The base text direction is left-to-right

If the text contains right-to-left content, this will be considered an embedded right-to-left run. Non-directional leading and trailing characters (e.g. a full stop) will normally not be included within this right-to-left section.

This uses Unicode TR9 HL1 to set an explicit paragraph embedding level of 0.

Rtl = 1

The base text direction is right-to-left

If the text contains left-to-right content, this will be considered an embedded left-to-right run. Non-directional leading and trailing characters (e.g. a full stop) will normally not be included within this left-to-right section.

This uses Unicode TR9 HL1 to set an explicit paragraph embedding level of 1.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Direction

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

Formats the value using the given formatter.

impl Default for Direction

fn default() -> Direction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Direction

fn deserialize<__D>( __deserializer: __D, ) -> Result<Direction, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Direction

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Direction

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

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

fn partial_cmp(&self, other: &Direction) -> 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 Serialize for Direction

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Direction

impl Eq for Direction

impl StructuralPartialEq for Direction
