Enum druid_shell::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.
