Is asn1 encoder broken?

Help
1

Hello everyone. am working on something with SNMP and i wanted to use the ASN1 module from the std lib however when i tried to run this example i got this error message

pub fn main(init: std.process.Init) !void {
    const arena = init.arena;
    defer arena.deinit();

    const allocator = arena.allocator();

    const num: i32 =  20;

    var encoder = asn1.der.Encoder.init(allocator);

    try encoder.any(num); 
}

Error:
