Struct ReduceImpl 

pub struct ReduceImpl {
    pub binary_scalar_func_type: TypeId,
    pub scalar_type: TypeId,
    pub vector_type: TypeId,
}

Implementation of a “reduce this vector by this binary operator to yield a scalar” FuncImpl for the given TypeIds of the binary scalar operator, the scalar type, and the vector type.

Fields

binary_scalar_func_type: TypeId

scalar_type: TypeId

vector_type: TypeId

Trait Implementations

impl Clone for ReduceImpl

fn clone(&self) -> ReduceImpl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl FuncImpl for ReduceImpl

fn evaluate( &self, state: &mut InterpreterState<'_>, args: Vec<TermReference>, ) -> (TermReference, NewlyEvaluatedTerms)

Given a handle on the current InterpreterState (primarily useful if additional terms need to be evaluated / looked up) and the collection of TermReference arguments to apply this function implementation to, yields a TermReference to the result, along with a collection of any NewlyEvaluatedTerms which may have arisen as part of the implementation of this method. See func_impl.rs in the source for sample implementations.

impl HasFuncSignature for ReduceImpl

fn get_name(&self) -> String

Gets the name for the implemented function.

fn required_arg_types(&self) -> Vec<TypeId>

Gets the list of required argument types for the implemented function.

fn ret_type(&self) -> TypeId

Gets the return type for the implemented function.

fn ready_to_evaluate(&self, args: &Vec<TermReference>) -> bool

Given a collection of TermReferences, determines whether we have sufficiently-many arguments to fully evaluate this function.

fn func_type(&self, type_info_directory: &TypeInfoDirectory) -> TypeId

Given a TypeInfoDirectory, obtains the TypeId which corresponds to the type of this implemented function.
