Write a boolean to the DER writer

pub fn integer<'b>(&mut self, integer: &'b Integer) -> Result<(), Error>

Write an Integer to the DER writer

pub fn enumerated<'b>(
    &mut self,
    enumerated: &'b Enumerated
) -> Result<(), Error>

Write an Enumerated to the DER writer

pub fn bitstring<'b>(&mut self, obj: &'b BitString) -> Result<(), Error>

Write a bitstring to the DER writer

pub fn octetstring<'b>(&mut self, obj: &'b [u8]) -> Result<(), Error>

Write a octetstring to the DER writer

pub fn null(&mut self) -> Result<(), Error>
