This crate contains the partial!
macro which allows partial application of a function.
Calling partial!(some_fn(arg0, _, arg2, _))
will return the closure
|x1, x3| some_fn(arg0, x1, arg1, x3)
.
The function call parentheses are optional:
partial!(some_fn arg0, _, arg2, _)
Move closures can be created by adding move
in front of the function: partial!(move ..)
```rust
extern crate partial_application;
fn foo(a: i32, b: i32, c: i32, d: i32, mul: i32, off: i32) -> i32 { (a + b*b + c.pow(3) + d.pow(4)) * mul - off }
fn main() { let bar = partial!( foo(, _, 10, 42, 10, 10) ); asserteq!( foo(15, 15, 10, 42, 10, 10), bar(15, 15) ); } ```
