Module registry 

Function registry: known function signatures for DSL validation.

Each registered function declares its name, category, expected wire inputs, constant parameters, output count, and variadic behavior. The compiler uses this to validate calls at parse time and to generically dispatch variadic functions.

Categories are a type-safe enum — every function must declare one. Categories group the registry for listings (by_category). The stdlib files carry a // @category: Name line for readers; FuncCategory::parse maps that text but no compile path consumes it.

Signatures are owned by their respective node modules. This file defines the shared types and the collector function.

Structs

FuncSig

Description of a registered function’s signature.

NodeRegistration

A node module’s registration: signatures + builder.

ParamSpec

Describes one parameter in a function’s call signature.

Enums

Arity

Arity specification for a function signature.

DefaultResolver

Auto-resolver kind attached to handle-taking functions. Tells the binding compiler which resolver to splice in when a string source is wired to a handle input port.

FuncCategory

Functional category for a Polydat node function.

OutputType

Output-type contract for a registered function.

Functions

by_category

Return functions grouped by category in display order.

lookup

Find a registered function by name.

registry

Return the full registry of known functions.

suggest_function

Find the closest function name to a misspelling.

Type Aliases

NodeBuildFn

Builder for a node module: (name, wires, resolved wire port types, const args) -> Some(Ok(node)) / Some(Err(msg)), or None when the name isn’t handled by this module.
