Struct FunctionRegistry 

pub struct FunctionRegistry { /* private fields */ }

Registry of named functions for serialization-safe custom transforms.

Provides the bridge between the non-serializable Transform::Custom(Arc<dyn Fn>) and the serializable TransformDef::NamedFunction { name, params }.

Example

use rill_patchbay::function_registry::FunctionRegistry;

let reg = FunctionRegistry::builtin();
let out = reg.apply("tanh", 0.5, &Default::default()).unwrap();
assert!((out - 0.5f64.tanh()).abs() < 1e-10);

Implementations

impl FunctionRegistry

pub fn new() -> Self

Create an empty registry.

pub fn register(&mut self, name: impl Into<String>, f: NamedFunction)

Register a named function.

pub fn apply( &self, name: &str, input: f64, params: &HashMap<String, f64>, ) -> Option<f64>

Apply a named function.

Returns None if the function name is not registered.

pub fn builtin() -> Self

Fill with built-in functions.

Trait Implementations

impl Clone for FunctionRegistry

fn clone(&self) -> FunctionRegistry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for FunctionRegistry

fn default() -> Self

Returns the “default value” for a type.
