The partial!
macro allows for partial application of a function.
partial!(some_fn => arg0, _, arg2, _)
returns the closure |x1, x3| some_fn(arg0, x1, arg2, x3)
.
Move closures are created by adding move
in front of the function: partial!(move ..)
```rust use partial_application::partial;
// When you're using the 2015 edition of Rust, you need to import the macro like this
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) ); } ```
