1//! Render gate backend interface.
2//!
3//! This interface defines the low-level API render gates must implement to be usable.
4//!
5//! A render gate is a special kind of pipeline node that allows to group renders behind a shared [`RenderState`]. All
6//! subsequent nodes in the pipeline will be using that render state.
