Function order [src]

Compares two slices of numbers lexicographically. O(n).

Prototype

pub fn order(comptime T: type, lhs: []const T, rhs: []const T) math.Order

Parameters

T: typelhs: []const Trhs: []const T

Example

 test order {
    try testing.expect(order(u8, "abcd", "bee") == .lt);
    try testing.expect(order(u8, "abc", "abc") == .eq);
    try testing.expect(order(u8, "abc", "abc0") == .lt);
    try testing.expect(order(u8, "", "") == .eq);
    try testing.expect(order(u8, "", "a") == .lt);
}

Source

  pub fn order(comptime T: type, lhs: []const T, rhs: []const T) math.Order {
    const n = @min(lhs.len, rhs.len);
    for (lhs[0..n], rhs[0..n]) |lhs_elem, rhs_elem| {
        switch (math.order(lhs_elem, rhs_elem)) {
            .eq => continue,
            .lt => return .lt,
            .gt => return .gt,
        }
    }
    return math.order(lhs.len, rhs.len);
}
