}Expand description
Rules: Width returned from measure has to be matched in draw given the same constraint (even if there’s some preferred height).
Required Methods§
fn measure(&self, ctx: MeasureCtx<'_>) -> ElementSize
fn draw(&self, ctx: DrawCtx<'_, '_>) -> ElementSize

Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
