Struct SliceWriter 

pub struct SliceWriter<'a> { /* private fields */ }

Writer which encodes DER into a mutable output byte slice.

Implementations

impl<'a> SliceWriter<'a>

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

Create a new encoder with the given byte slice as a backing buffer.

pub fn encode<T: Encode>(&mut self, encodable: &T) -> Result<()>

Encode a value which impls the Encode trait.

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

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

pub fn is_failed(&self) -> bool

Did the decoding operation fail due to an error?

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

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

pub fn context_specific<T>( &mut self, tag_number: TagNumber, tag_mode: TagMode, value: &T, ) -> Result<()>

where T: EncodeValue + Tagged,

Encode a CONTEXT-SPECIFIC field with the provided tag number and mode.

pub fn sequence<F>(&mut self, length: Length, f: F) -> Result<()>

where F: FnOnce(&mut SliceWriter<'_>) -> Result<()>,

Encode an ASN.1 SEQUENCE of the given length.

Spawns a nested slice writer which is expected to be exactly the specified length upon completion.

Trait Implementations

impl<'a> Debug for SliceWriter<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Writer for SliceWriter<'a>

fn write(&mut self, slice: &[u8]) -> Result<()>

Write the given DER-encoded bytes as output.

fn write_byte(&mut self, byte: u8) -> Result<()>

Write a single byte.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
