Struct ssh_encoding::base64::Base64Reader

pub struct Base64Reader<'i> { /* private fields */ }

Available on crate feature base64 only.

Constant-time Base64 reader implementation.

Implementations

impl<'i> Base64Reader<'i>

pub fn new(input: &'i [u8]) -> Result<Self>

Create a new Base64 reader for a byte slice containing contiguous (non-newline-delimited) Base64-encoded data.

Returns

• Ok(reader) on success.
• Err(Error::Base64) if the input buffer is empty.

Trait Implementations

impl Reader for Base64Reader<'_>

fn read<'o>(&mut self, out: &'o mut [u8]) -> Result<&'o [u8]>

Read as much data as is needed to exactly fill out.

fn read_prefixed<T, E, F>(&mut self, f: F) -> Result<T, E>

where E: From<Error>, F: FnOnce(&mut Self) -> Result<T, E>,

Decode length-prefixed data.

fn remaining_len(&self) -> usize

Get the length of the remaining data after Base64 decoding.

fn is_finished(&self) -> bool

Is decoding finished?

fn read_byten<'o>(&mut self, out: &'o mut [u8]) -> Result<&'o [u8]>

Decodes [u8] from byte[n] as described in RFC4251 § 5:

fn read_string<'o>(&mut self, buf: &'o mut [u8]) -> Result<&'o str>

Decode a string as described in RFC4251 § 5:

fn drain(&mut self, n_bytes: usize) -> Result<()>

Drain the given number of bytes from the reader, discarding them.

fn drain_prefixed(&mut self) -> Result<usize>

Decode a u32 length prefix, and then drain the length of the body.

fn ensure_finished(&self) -> Result<()>

Ensure that decoding is finished.

fn finish<T>(self, value: T) -> Result<T>

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