Function lastIndexOfNone [src]

Find the last item in slice which is not contained in values. Like strspn in the C standard library, but searches from the end.

Prototype

pub fn lastIndexOfNone(comptime T: type, slice: []const T, values: []const T) ?usize

Parameters

T: typeslice: []const Tvalues: []const T

Source

  pub fn lastIndexOfNone(comptime T: type, slice: []const T, values: []const T) ?usize {
    var i: usize = slice.len;
    outer: while (i != 0) {
        i -= 1;
        for (values) |value| {
            if (slice[i] == value) continue :outer;
        }
        return i;
    }
    return null;
}
