fn as_(self) -> T;
}Expand description
A generic interface for casting between machine scalars with the
as operator, which admits narrowing and precision loss.
Implementers of this trait AsPrimitive should behave like a primitive
numeric type (e.g. a newtype around another primitive), and the
intended conversion must never fail.
§Examples
let three: i32 = (3.14159265f32).as_();
assert_eq!(three, 3);§Safety
In Rust versions before 1.45.0, some uses of the as operator were not entirely safe.
In particular, it was undefined behavior if
a truncated floating point value could not fit in the target integer
type (#10184).
