This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig library itself.

rotate

In-place rotation of the values in an array ([0 1 2 3] becomes [1 2 3 0] if we rotate by 1) Assumes 0 <= amount <= items.len

mem.rotate

lib/std/mem.zig:4044

Code

pub fn rotate(comptime T: type, items: []T, amount: usize) void {
    reverse(T, items[0..amount]);
    reverse(T, items[amount..]);
