Struct Decoder 

pub struct Decoder<'i> {
    type_label: &'i str,
    base64: Decoder<'i, Base64>,
}

Buffered PEM decoder.

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

Fields

type_label: &'i str

base64: Decoder<'i, Base64>

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

Create a new PEM Decoder which automatically detects the line width the input is wrapped at and flexibly handles widths other than the default 64-characters.

Note: unlike new and new_wrapped, this method is not constant-time.

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>

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?

Trait Implementations

impl<'i> Clone for Decoder<'i>

fn clone(&self) -> Decoder<'i>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'i> From<Decoder<'i>> for Decoder<'i, Base64>

fn from(decoder: Decoder<'i>) -> Decoder<'i, Base64>

Converts to this type from the input type.
