Trait TryFromByAdd 

pub trait TryFromByAdd<T> {
    // Required method
    fn try_from_by_add(n: T) -> Option<Self>
       where Self: Sized;
}

Generic trait for converting between integer types within bounds of possible values.

• For all integer types in the range of possible values.
• Returns an error if the value is out of range.
• Converting types with different signs of the same size in bits.
• A normal conversion of same-signed types to a larger integral type.
• It is possible to convert types with different signs to a larger integer type.

Usage

Basic use of the trait.

use num_convert::TryFromByAdd;

assert_eq!(<u8 as TryFromByAdd<i16>>::try_from_by_add(-128_i16).unwrap(), 0_u8);
assert_eq!(<u8>::try_from_by_add(127_i8).unwrap(), 255_u8);

Examples

Converting without error.

assert_eq!(<u32 as TryFromByAdd<i8>>::try_from_by_add(<i8>::MIN), Some(<u8>::MIN as u32));
assert_eq!(<u64 as TryFromByAdd<i8>>::try_from_by_add(<i8>::MAX), Some(<u8>::MAX as u64));

Converting with error.

assert_eq!(<u32>::try_from_by_add(<u64>::MAX), None);
assert_eq!(<u8>::try_from_by_add(128_i16), None);

Required Methods

fn try_from_by_add(n: T) -> Option<Self>

where Self: Sized,

Converts the value from T to self.
