Struct derp::Der
[−]
[src]
pub struct Der<'a, W: Write + 'a> { /* fields omitted */ }
Helper for writing DER that automattically encoes tags and content lengths.
Methods
impl<'a, W: Write> Der<'a, W>[src]
fn new(writer: &'a mut W) -> Self
Create a new Der structure that writes values to the given writer.
fn write_null(&mut self) -> Result<()>
Write a NULL tag.
fn write_element(&mut self, tag: Tag, input: &[u8]) -> Result<()>
Write an arbitrary element.
fn write_integer(&mut self, input: &[u8]) -> Result<()>
Write the given input as an integer.
fn write_positive_integer(&mut self, input: &[u8]) -> Result<()>
Write the given input as a positive integer.
fn write_sequence<F: FnOnce(&mut Der<Vec<u8>>) -> Result<()>>(
&mut self,
func: F
) -> Result<()>
&mut self,
func: F
) -> Result<()>
Write a SEQUENCE by passing in a handling function that writes to an intermediate Vec
before writing the whole sequence to self.
fn write_raw(&mut self, input: &[u8]) -> Result<()>
Write raw bytes to self. This does not calculate length or apply. This should only be used
when you know you are dealing with bytes that are already DER encoded.
fn write_bit_string<F: FnOnce(&mut Der<Vec<u8>>) -> Result<()>>(
&mut self,
unused_bits: u8,
func: F
) -> Result<()>
&mut self,
unused_bits: u8,
func: F
) -> Result<()>
Write a BIT STRING by passing in a handling function that writes to an intermediate Vec
before writing the whole sequence to self.
