Method read_cstr

src/pgwire-common/src/codec.rs:278–286

Returns the next null-terminated string. The null character is not included the returned string. The cursor is advanced past the null- terminated string. If there is no null byte remaining in the string, returns `CodecError::StringNoTerminator`. If the string is not valid UTF-8, returns an `io::Error` with an error kind of `io::ErrorKind::InvalidInput`. NOTE(benesch): it is possible that returni
