Macro exmex::ops_factory [−][src]
macro_rules! ops_factory {
($name : ident, $T : ty, $($ops : expr), *) => { ... };
}
Expand description
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 Operator
s 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())
);
