DER encoder.

Implementations

impl<'a> Encoder<'a>[src]

pub fn new(bytes: &'a mut [u8]) -> Self[src]

pub fn encode<T: Encodable>(&mut self, encodable: &T) -> Result<()>[src]

Encode a value which impls the Encodable trait.

pub fn error<T>(&mut self, kind: ErrorKind) -> Result<T>[src]

Return an error with the given ErrorKind, annotating it with context about where the error occurred.

pub fn is_failed(&self) -> bool[src]

Did the decoding operation fail due to an error?

pub fn finish(self) -> Result<&'a [u8]>[src]

Finish encoding to the buffer, returning a slice containing the data written to the buffer.
