Struct StreamEncoder 

pub struct StreamEncoder<W: Write> { /* private fields */ }

A stream encoder that implements StreamDecodee. Using this, a ASN.1 stream can be written using a SAXParser style interface.

Implementations

impl<W: Write> StreamEncoder<W>

pub fn new<T: Into<ByteWriter<W>>>(writer: T) -> Self

Trait Implementations

impl<W: Write> StreamDecodee for StreamEncoder<W>

fn start_element(&mut self, tag: Tag, len: Len) -> ParseResult

This function is called when an ASN.1 tag is encountered. In other words, at the start of an ASN.1 element.

fn end_element(&mut self, _: Tag, _: Len) -> ParseResult

This function is called when an ASN.1 element has finished decoding. Note that this is also called for all elements, even after a primitive() call. For this reason, you may need to check the constructed flag in some cases.

fn primitive<I: Iterator<Item = Result<u8>>>( &mut self, reader: &mut ByteReader<I>, len: LenNum, ) -> ParseResult

This function is called when a primitive element is encountered. Note that both start_element and end_element are called before/after this function.

fn warning(_: DecodeError) -> ParseResult

This function would be called when a recoverable decode error occurs, however currently nothing calls this.

fn error(_: DecodeError)

This function would be called when a fatal decoding error occurs, however currently nothing calls this.
