Concatenate a tuple of arrays (or references to an array) into a single array
The concat_arrays function allows you to concatenate an arbitrary (up to 10) static arrays into one final array.
use function_concat_array_tuple::concat_arrays;
assert_eq!(concat_arrays(([1u8], [2])), [1u8, 2]);
assert_eq!(concat_arrays((&[1u8], &[2])), [1u8, 2]);The concat_arrays function takes a const N: usize parameter.
This parameter will often be infered from context.
The N const parameter must be equal to the sum of the length of the arrays.
For safety, there is a compile-time check that this is correct.
The following would fail to compile:
use function_concat_array_tuple::concat_arrays;
let _: [u8; 3] = concat_arrays(([1], [2]));use function_concat_array_tuple::concat_arrays;
let _: [u8; 3] = concat_arrays((&[1], &[2]));Due to const functions in traits not being possible, this does not work in a const context. It is however possible
