Function parse_rsa_algorithm_attributes 

Source 
pub fn parse_rsa_algorithm_attributes(
    attr: &[u8],
) -> Result<RsaAttributes, ParseError>
Expand description

Parse the RSA algorithm attributes (01 | n_bits | e_bits | [format]).

The leading byte must be 0x01 (RSA). The format byte is optional: a 5-byte attribute (no format byte) is treated as RsaImportFormat::Standard, per the spec and GnuPG. Returns ParseError::UnsupportedAlgorithm for a non-RSA object, ParseError::UnexpectedLength for a short/garbled one.
