Struct FunctionMap 

pub struct FunctionMap<T: EvaluationDomain> { /* private fields */ }

A map of named functions that can be called during evaluation.

Implementations

impl<T: EvaluationDomain> FunctionMap<T>

pub fn new() -> Self

Create an empty function map.

pub fn register( &mut self, name: &str, arity: usize, func: Box<dyn Fn(&[T]) -> T + Send + Sync>, )

Register a function with the given name and arity.

pub fn register_alias(&mut self, alias: &str, canonical: &str)

Register an alias for a function name.

pub fn resolve(&self, name: &str) -> Option<&FunctionEntry<T>>

Look up a function by name (resolving aliases and case).

pub fn index_of(&self, name: &str) -> Option<usize>

Get the index of a function by name.

pub fn call_by_index(&self, idx: usize, args: &[T]) -> Option<T>

Call a function by its index in the map.

pub fn len(&self) -> usize

Return the number of registered functions.

pub fn is_empty(&self) -> bool

Return true if no functions are registered.

Trait Implementations

impl<T: EvaluationDomain> Default for FunctionMap<T>

fn default() -> Self

Returns the “default value” for a type.
