Trait Layoutable 

pub trait Layoutable {
    // Required methods
    fn measure(&self, ctx: &LayoutCtx<'_>, constraints: Constraints) -> Size;
    fn layout(
        &self,
        ctx: &LayoutCtx<'_>,
        area: Rect,
        warnings: &mut Vec<LayoutWarning>,
        page: usize,
    ) -> LayoutResult;
}

measure/layout. Implemented for every concrete element type (not Element variants with todo!(), since all V1-through-Phase-2 variants are implemented) plus a dispatching impl on Element itself so containers can recurse over Vec<Element> children.

Required Methods

fn measure(&self, ctx: &LayoutCtx<'_>, constraints: Constraints) -> Size

fn layout( &self, ctx: &LayoutCtx<'_>, area: Rect, warnings: &mut Vec<LayoutWarning>, page: usize, ) -> LayoutResult

Dyn Compatibility

This trait is dyn compatible.

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