Struct DrawReceiver

pub struct DrawReceiver<S: Schema> { /* private fields */ }

A receiver for drawing layout objects.

Implements the primitive functions that layout objects need to implement Draw.

Implementations

impl<S: Schema> DrawReceiver<S>

pub fn draw(&mut self, obj: impl Draw<S>) -> Result<()>

Draw layout object obj.

For instances, a new thread is spawned to add the instance once the underlying cell has been generated. If generation fails, the spawned thread may panic after this function has been called.

For error recovery, instance generation results should be checked using Instance::try_cell before calling draw.

Panics

May cause a panic if generation of an underlying instance fails.
