Crate num_convert

Generic traits for conversions between integer types.

This library provides various ways to convert to integer type from other types.

Examples

assert_eq!(<u8 as FromByAdd<i8>>::from_by_add(-128_i8), 0_u8);
assert_eq!(<i16 as IntoByAdd<u16>>::into_by_add(i16::MIN), u16::MIN);

assert_eq!(<i8 as TryFromByAdd<u8>>::try_from_by_add(0_u8), Some(-128_i8));
assert_eq!(<i128 as TryIntoByAdd<u128>>::try_into_by_add(i128::MIN), Some(u128::MIN));

assert_eq!(<u8 as FromAs<i8>>::from_as(-128_i8), 128_u8);
assert_eq!(<u16 as IntoAs<u8>>::into_as(258_u16), 2_u8);

assert_eq!(<u8 as TryFromDigits<u16>>::from_digits(65_255_u16), Ok(255_u8));

assert_eq!(u64::MAX.sbits(), 64_u32);
assert_eq!(i8::tbits(), 8_u32);

assert_eq!(0i8.len(), 1_usize);
assert_eq!(u128::MAX.len(), 39_usize);

assert_eq!(<i32 as FromTuple>::from_5((true, false, 45_u8, 2023_u16, -60_i8,)),
[1_i32, 0_i32, 45_i32, 2023_i32, -60_i32]);

assert_eq!(<i16 as TryFromIntStr<&str>>::try_from_int_str("-2023"), Ok(-2023_i16));
assert_eq!(<u16 as TryFromIntStr<u128>>::try_from_int_str(1975_u128), Ok(1975_u16));
