Function indexOfNone [src]

Find the first item in slice which is not contained in values. Comparable to strspn in the C standard library.

Prototype

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

Parameters

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

Example

 test indexOfNone {
    try testing.expect(indexOfNone(u8, "abc123", "123").? == 0);
    try testing.expect(lastIndexOfNone(u8, "abc123", "123").? == 2);
    try testing.expect(indexOfNone(u8, "123abc", "123").? == 3);
    try testing.expect(lastIndexOfNone(u8, "123abc", "123").? == 5);
    try testing.expect(indexOfNone(u8, "123123", "123") == null);
    try testing.expect(indexOfNone(u8, "333333", "123") == null);

    try testing.expect(indexOfNonePos(u8, "abc123", 3, "321") == null);
}
