Struct BuiltinSig 

pub struct BuiltinSig {
    pub name: &'static str,
    pub params: Vec<ParamType>,
    pub signal_outs: usize,
    pub kind: BuiltinKind,
    pub param_names: Vec<&'static str>,
}

Type-checker-facing signature of a built-in (independent of T).

Fields

name: &'static str

Registered name.

params: Vec<ParamType>

Parameter list: first N entries are signal inputs, remainder are compile-time params.

signal_outs: usize

Number of signal outputs (1 in this increment).

kind: BuiltinKind

Sample vs block.

param_names: Vec<&'static str>

Names of compile-time parameters in params order (after signal inputs). When non-empty, graph-level build_ir() uses these names to match recipe params to builtin arg positions — eliminating ordering fragility from HashMap-based param bags. Left empty for backward-compatible registrations.

Implementations

impl BuiltinSig

pub fn simple( name: &'static str, signal_ins: usize, signal_outs: usize, num_params: usize, kind: BuiltinKind, ) -> Self

Convenience constructor for SISO built-ins with only Float params. Maintains backward compatibility during migration.

pub fn with_names(self, names: Vec<&'static str>) -> Self

Attach human-readable names to compile-time parameters.

names.len() must equal the number of non-signal params in self.params. When set, graph-level build_ir() in rill-graph uses these names to match recipe param keys to builtin arg positions, fixing the ordering fragility of HashMap-based param bags.

pub fn signal_ins(&self) -> usize

Number of signal inputs = count of Signal params (non-variadic).

pub fn min_args(&self) -> usize

Minimum number of Apply arguments (excludes Signal params).

pub fn max_args(&self) -> Option<usize>

Maximum number of Apply arguments (None if variadic; excludes Signal params).
