pub fn abs<T: Signed>(value: T) -> T
Computes the absolute value.
For f32 and f64, NaN will be returned if the number is NaN
For signed integers, ::MIN will be returned if the number is ::MIN.
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, typedef (or
tdef).
Search functions by type signature (e.g.
vec -> usize)
