macro_rules! unimplemented { () => (panic!("not yet implemented")) }
A standardised placeholder for marking unfinished code. It panics with the
message "not yet implemented" when executed.
Prefix searches with a type followed by a colon (e.g.
fn:) to restrict the search to a given type.
Accepted types are: fn, mod,
struct, enum,
trait, type, macro,
and const.
Search functions by type signature (e.g.
vec -> usize)
