Macro exmex::ops_factory

macro_rules! ops_factory {
    ($name : ident, $T : ty, $($ops : expr), *) => { ... };
}

This macro creates an operator factory struct that implements the trait MakeOperators. You have to pass the name of the struct as first, the type of the operands as second, and the Operators as third to n-th argument.

Example

The following snippet creates a struct that can be used as in FlatEx<_, MyOpsFactory>.

use exmex::{MakeOperators, Operator, ops_factory};
ops_factory!(
    MyOpsFactory,  // name of struct
    f32,           // data type of operands
    Operator::make_unary("log", |a| a.ln()),
    Operator::make_unary("log2", |a| a.log2())
);
