Struct FnEvalRegistry 

pub struct FnEvalRegistry { /* private fields */ }

Registry of function-pointer callbacks for parallel evaluation of SymbolKind::Function nodes.

Keys are crate::dag::symbol::FnId values. The registered function receives a pointer to the variable array (same layout as JIT functions) and returns an f64.

Pass a &FnEvalRegistry to evaluate_node_with_fns to enable function-node evaluation in the parallel path.

Implementations

impl FnEvalRegistry

pub fn new() -> Self

Creates an empty registry.

pub fn register(&mut self, fn_id: FnId, f: fn(*const f64) -> f64)

Registers a function callback for fn_id.

pub fn get(&self, fn_id: FnId) -> Option<fn(*const f64) -> f64>

Looks up the callback for fn_id.

Trait Implementations

impl Default for FnEvalRegistry

fn default() -> FnEvalRegistry

Returns the “default value” for a type.
