pub struct Decoder<'i> { /* private fields */ }
Available on crate feature pkcs8 only.
Expand description

Buffered PEM decoder.

Stateful buffered decoder type which decodes an input PEM document according to RFC 7468’s “Strict” grammar.

Implementations§

§

impl<'i> Decoder<'i>

pub fn new(pem: &'i [u8]) -> Result<Decoder<'i>, Error>

Create a new PEM Decoder with the default options.

Uses the default 64-character line wrapping.

pub fn new_wrapped( pem: &'i [u8], line_width: usize ) -> Result<Decoder<'i>, Error>

Create a new PEM Decoder which wraps at the given line width.

pub fn type_label(&self) -> &'i str

Get the PEM type label for the input document.

pub fn decode<'o>(&mut self, buf: &'o mut [u8]) -> Result<&'o [u8], Error>

Decode data into the provided output buffer.

There must be at least as much remaining Base64 input to be decoded in order to completely fill buf.

pub fn decode_to_end<'o>( &mut self, buf: &'o mut Vec<u8> ) -> Result<&'o [u8], Error>

Available on crate feature alloc only.

Decode all of the remaining data in the input buffer into buf.

pub fn remaining_len(&self) -> usize

Get the decoded length of the remaining PEM data after Base64 decoding.

pub fn is_finished(&self) -> bool

Are we finished decoding the PEM input?
