Struct HintRegistry 

pub struct HintRegistry { /* private fields */ }

Registry for hint handlers keyed by HintId.

Each entry keeps the name it was registered under. An id shared by two names is then caught, instead of running one hint as the other.

Implementations

impl HintRegistry

pub fn new() -> Self

An empty registry.

pub fn register<T: Hint>(&mut self, handler: T) -> HintId

Register a hint, returning its HintId.

Registering a name already present is a no-op, the handler’s fields included.

Panics

Panics if a different name already holds this id.

pub fn shape(&self, hint_id: HintId, dimensions: &[usize]) -> (usize, usize)

Compute the (n_in, n_out) arity of the hint identified by hint_id.

pub fn execute( &self, hint_id: HintId, dimensions: &[usize], inputs: &[Word], outputs: &mut [Word], )

Run the handler under hint_id, writing its results into outputs.

Panics

Panics if nothing is registered under hint_id.

Trait Implementations

impl Default for HintRegistry

fn default() -> Self

Returns the “default value” for a type.
