Struct SimpleLayouter 

pub struct SimpleLayouter {
    pub flow_direction: FlowDirection,
}

Simple layouter that supports both horizontal (LTR) and vertical flow.

For horizontal flow, advances a cursor left-to-right, emitting a PositionedGlyph for each input glyph and wrapping when the cursor exceeds max_width.

For vertical flow, advances the cursor top-to-bottom using each glyph’s y_advance (falling back to x_advance when y_advance is zero), and wraps into a new column when max_width (treated as max column height) is exceeded.

Fields

flow_direction: FlowDirection

Text flow direction for this layouter instance.

Implementations

impl SimpleLayouter

pub fn new() -> Self

Creates a new layouter with horizontal flow (the default).

pub fn with_flow_direction(self, dir: FlowDirection) -> Self

Returns a copy of this layouter with the given flow direction.

pub fn layout( &self, runs: &[ShapedRun], constraints: &LayoutConstraints, ) -> Result<Vec<PositionedGlyph>, OxiTextError>

Positions glyphs from the shaped runs according to constraints.

Dispatches to Self::layout_horizontal or Self::layout_vertical based on Self::flow_direction.

Errors

Currently infallible; returns Err only for forward compatibility.

Trait Implementations

impl Default for SimpleLayouter

fn default() -> Self

Returns the “default value” for a type.
