pub struct Decoder<'a> { /* fields omitted */ }

DER decoder.

Implementations

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

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

Create a new decoder for the given byte slice.

pub fn decode<T: Decodable<'a>>(&mut self) -> Result<T>[src]

Decode a value which impls the Decodable 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<T>(self, value: T) -> Result<T>[src]

Finish decoding, returning the given value if there is no remaining data, or an error otherwise

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

Have we decoded all of the bytes in this Decoder?

Returns false if we’re not finished decoding or if a fatal error has occurred.

pub fn any(&mut self) -> Result<Any<'a>>[src]
