Struct DenseOperationTable 

pub struct DenseOperationTable { /* private fields */ }

A fixed 256-slot selector table with every missing selector pre-filled as NOP.

This removes the Option/match from the hot dispatch path. It is still not literally branchless at the CPU level, because calling a function pointer is an indirect branch. The useful property is that selector choice is table indexing rather than an if/else or match chain.

Implementations

impl DenseOperationTable

pub fn new() -> Self

Create a dense table full of NOP entries.

pub fn register( &mut self, selector: u8, name: &'static str, func: DenseOpFn, arg: DenseOpArg, )

Register a selector.

pub fn execute(&self, selector: u8, frame: OpFrame) -> DispatchResult<OpFrame>

Execute the selector. Missing entries execute NOP.

pub fn name(&self, selector: u8) -> &'static str

Return the static operation name registered for a selector.
