tiny.preserves.decodePacked

1/// Returns the one value that `bytes` encodes, allocated with `allocator`. Code that admits packed2/// bytes from a peer calls it, for one owned value within the caller's limits. `D` is the type of3/// the result's embedded values, and the decoder rejects embedded values whatever `D` is. The value4/// owns all its memory, so `bytes` may be freed at once, and the caller frees the value with5/// `deinit`. On any error the call frees everything it allocated. Its duplicate checks compare each6/// set element or dictionary key with every earlier one, so their cost grows with the square of the7/// count.8pub fn decode(9    comptime D: type,10    allocator: Allocator,11    bytes: []const u8,12    limits: Limits,13) DecodeError!value_mod.Value(D) {14    var index: usize = 0;15    var admission = Admission{ .limits = limits };16    var value = try readValue(D, allocator, bytes, &index, &admission, 1);17    errdefer value.deinit(allocator);18    if (index != bytes.len) return error.UnexpectedTrailingBytes;19    return value;20}
