Macro incomplete::incomplete
[−]
[src]
macro_rules! incomplete { ($ty:ty) => { ... }; () => { ... }; }
Indicate that a segment of code must be filled out before compilation is allowed to succeed.
Examples
#[macro_use] extern crate incomplete; fn main() { let x = incomplete!(bool); if x == true { println!("profit"); } }
would produce
error: value assigned to `incomplete` is never read
--> src/main.rs:5:13

5 | let x = incomplete!(bool);

You can leave the type argument out if the compiler can already infer the type. ```
