Function tls_parser::parse_content_and_signature

pub fn parse_content_and_signature<'a, F, T: 'a>(
    i: &'a [u8], 
    fun: F, 
    ext: bool
) -> IResult<&'a [u8], (T, DigitallySigned<'_>)> where
    F: Fn(&'a [u8]) -> IResult<&[u8], T>, 

Parse DigitallySigned object, depending on the ext parameter which should be true if the TLS client has sent the signature_algorithms extension
