Macro concat_arrays::concat_arrays

concat_arrays!() { /* proc-macro */ }

Concatenates arrays.

Example

let x = [0];
let y = [1, 2];
let z = [3, 4, 5];
let concatenated = concat_arrays!(x, y, z);
assert_eq!(concatenated, [0, 1, 2, 3, 4, 5]);

Limitations

Due to limitations in rust concat_arrays! can’t tell the compiler what the length of the returned array is. As such, the length needs to be inferable from the surrounding context. For example, in the example above the length is inferred by the call to assert_eq!. It is safe to mis-specify the length however since you’ll get a compilation error rather than broken code.
