Trait num_conv::CastUnsigned
source · pub trait CastUnsigned: Integer {
type Unsigned;
// Required method
fn cast_unsigned(self) -> Self::Unsigned;
}Expand description
Cast to an unsigned integer of the same size.
This trait is implemented for all integers. Signed to unsigned casts are equivalent to
0.wrapping_add_unsigned(value), while unsigned to unsigned casts are an identity conversion.
