Expand description

Represents a two-dimensional value that can be converted to a pixel value in a LAYOUT context.

Required Associated Types§

Source

type Px: Default

Pixel type.

Required Methods§

Source

fn layout_dft(&self, default: Self::Px) -> Self::Px

Compute the pixel value in the current LAYOUT context with default.

Source

fn affect_mask(&self) -> LayoutMask

Compute a LayoutMask that flags all contextual values that affect the result of layout.

Provided Methods§

Source

fn layout(&self) -> Self::Px

Compute the pixel value in the current LAYOUT context.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
