Enum druid::text::Direction

pub enum Direction {
    Left,
    Right,
    Upstream,
    Downstream,
}

Indicates a horizontal direction in the text.

Variants

Left

The direction visually to the left.

This may be byte-wise forwards or backwards in the document, depending on the text direction around the position being moved.

Right

The direction visually to the right.

This may be byte-wise forwards or backwards in the document, depending on the text direction around the position being moved.

Upstream

Byte-wise backwards in the document.

In a left-to-right context, this value is the same as Left.

Downstream

Byte-wise forwards in the document.

In a left-to-right context, this value is the same as Right.

Implementations

impl Direction

pub fn is_upstream_for_direction(self, direction: WritingDirection) -> bool

Returns true if this direction is byte-wise backwards for the provided WritingDirection.

The provided direction must not be WritingDirection::Natural.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a copy 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 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 PartialEq<Direction> for Direction

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
