For parsing a JSON stream, e.g., when using Angstrom_async.parse_many, you should instead use t_without_trailing_whitespace.

t_without_trailing_whitespace will parse a single JSON value without consuming any trailing whitespace. This is useful in the context of streaming multiple JSON values because it will immediately return t when it is parsed, but it may fail in other parsing contexts where the input buffer is expected to be fully consumed.
