Type Alias LineSpacing

pub type LineSpacing = Length;

Extra spacing in-between text lines.

The Default value is zero. Relative values are calculated from the LineHeight, so 50.pct() is half the computed line height.

Variants

Default

The default (initial) value.

Dip(Dip)

The exact length in device independent units.

Px(Px)

The exact length in device pixel units.

Pt(f32)

The exact length in font points.

Factor(Factor)

Relative to the fill length.

Leftover(Factor)

Relative to the leftover fill length.

Em(Factor)

Relative to the font-size of the widget.

RootEm(Factor)

Relative to the font-size of the root widget.

ViewportWidth(Factor)

Relative to the width of the nearest viewport ancestor.

ViewportHeight(Factor)

Relative to the height of the nearest viewport ancestor.

ViewportMin(Factor)

Relative to the smallest of the nearest viewport ancestor’s dimensions.

ViewportMax(Factor)

Relative to the smallest of the nearest viewport ancestor’s dimensions.

DipF32(f32)

The exact length in device independent units, defined using a f32 value.

This value will be rounded to the nearest pixel after layout, but it will be used as is in the evaluation of length expressions.

PxF32(f32)

The exact length in device pixel units, defined using a f32 value.

This value will be rounded to the nearest pixel after layout, but it will be used as is in the evaluation of length expressions.

Expr(Box<LengthExpr>)

Expression.
