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

/// Render gate and associated [`RenderState`].

  /// Enter the [`RenderGate`] and share the [`RenderState`] for all subsequent nodes in the pipeline.
