Module malachite_base::num::conversion::slice

Traits for converting slices to numbers, slices to [Vec]s, or numbers to [Vec]s. The traits are FromOtherTypeSlice, VecFromOtherTypeSlice, and VecFromOtherType.

from_other_type_slice

use malachite_base::num::conversion::traits::FromOtherTypeSlice;

let xs: &[u32] = &[];
assert_eq!(u32::from_other_type_slice(xs), 0);
assert_eq!(u32::from_other_type_slice(&[123u32, 456]), 123);

assert_eq!(u8::from_other_type_slice(&[0xabcdu16, 0xef01]), 0xcd);

assert_eq!(u16::from_other_type_slice(&[0xabu8, 0xcd, 0xef]), 0xcdab);
assert_eq!(u64::from_other_type_slice(&[0xabu8, 0xcd, 0xef]), 0xefcdab);

vec_from_other_type_slice

use malachite_base::num::conversion::traits::VecFromOtherTypeSlice;

assert_eq!(u32::vec_from_other_type_slice(&[123u32, 456]), &[123, 456]);
assert_eq!(
    u8::vec_from_other_type_slice(&[0xcdabu16, 0x01ef, 0x4523, 0x8967]),
    &[0xab, 0xcd, 0xef, 0x01, 0x23, 0x45, 0x67, 0x89]
);
assert_eq!(
    u16::vec_from_other_type_slice(&[0xabu8, 0xcd, 0xef, 0x01, 0x23, 0x45, 0x67]),
    &[0xcdab, 0x01ef, 0x4523, 0x67]
);

vec_from_other_type

use malachite_base::num::conversion::traits::VecFromOtherType;

assert_eq!(u32::vec_from_other_type(123u32), &[123]);
assert_eq!(u8::vec_from_other_type(0xcdabu16), &[0xab, 0xcd]);
assert_eq!(u16::vec_from_other_type(0xabu8), &[0xab]);
