ToUnit; drop to the trash syntax sugar for any types.
Example
``rust
use to_unit::ToUnit;
// or,use tounit::ToUnit as _` for ultra lay persons!
[test]
fn matcharmstoeasily()
{
use std::collections::HashMap;
let mut x = HashMap::::new();
x.insert("neko".tostring(), 123);
match x.getmut("neko")
{
Some(v) => *v = 222,
None => x.insert("neko".tostring(), 222).tounit() // <-- here!
}
// Ofcorse alternatively, you can write:
// eg. None => { x.insert("neko".tostring(), 222); }
// But, it might be fix to a multi-line format by rust-fmt then...:
// eg. None => {
// x.insert("neko".tostring(), 222);
// }
// I don't like the multi-line behaviors, so I made the _ lib.
//
}
