Module fetish_lib::func_impl

Structs

AddOperator	BinaryArrayOperator for vector addition.
BinaryFuncImpl	Wrapper around a BinaryArrayOperator to conveniently lift it to a FuncImpl given the TypeId of the argument/return type.
ComposeImpl	Implementation of a “function composition” FuncImpl
ConstImpl	Implementation of the constant function for the given “return” and “ignored” types. The result is of type return -> ignored -> return.
FillImpl	Implementation of a “Fill a vector with the given scalar” FuncImpl for the given scalar and vector TypeIds.
HeadImpl	Implementation of a “get the first element of a vector” FuncImpl for the given vector and scalar types.
MapImpl	Implementation of a “map this scalar function over every element of a vector” FuncImpl for the given scalar type, scalar function type, and vector type.
MulOperator	BinaryArrayOperator for elementwise vector multiplication.
ReduceImpl	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.
RotateImpl	Implementation of a “rotate left one index” FuncImpl for a given vector TypeId. (That is, given [x_1, x_2, ...], rotates to [x_2, x_2, ... x_1].
SetHeadImpl	Implementation of a “set the first element of a vector to the given one” FuncImpl for the given vector and scalar types.
SubOperator	BinaryArrayOperator for vector subtraction.

Traits

BinaryArrayOperator	Trait to ease implementation of primitive binary operators which have identical argument types and return type. To be used in tandem with BinaryFuncImpl.
FuncImpl	Trait for primitive function implementations.
HasFuncSignature	Trait which gives a “signature” for functions to be included in a crate::primitive_directory::PrimitiveDirectory. This consists of a name, a collection of required argument types, and a return type. Primitive functions are assumed to be uniquely identifiable from their particular implementation of this trait.
