Expand description

Trait for generic node implementations processing one buffer at a time in a feature arc

Required Methods§

Source

unsafe fn map_buffer_to_next_x4( &self, vm: &MainRef, node: &mut NodeRuntimeRef<N>, b: &mut [&mut BufferRef<N::FeatureData>; 4], ) -> [FeatureNextNode<N::NextNodes>; 4]

Process four buffers and determining the next nodes to send them to

§Safety

The safety preconditions vary depending on the specific implementation.

Provided Methods§

Source

fn prefetch_buffer_x4( &self, _vm: &MainRef, _node: &mut NodeRuntimeRef<N>, b: &mut [&mut BufferRef<N::FeatureData>; 4], )

Performing prefetching for a given buffer

Source

unsafe fn trace_buffer( &self, _vm: &MainRef, _node: &mut NodeRuntimeRef<N>, _b0: &mut BufferRef<N::FeatureData>, )

Trace a buffer

This is optional and can be empty if tracing is implemented in GenericFeatureNodeX4::map_buffer_to_next_x4 and GenericFeatureNodeX1::map_buffer_to_next instead.

§Safety

The safety preconditions vary depending on the specific implementation.

Dyn Compatibility§

This trait is dyn compatible.

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