Struct age::armor::ArmoredReader

pub struct ArmoredReader<R> { /* private fields */ }

Reader that will parse the age ASCII armor format if detected.

Examples

use std::io::Read;
use std::iter;

let identity = load_identity()?;
let encrypted = load_encrypted_file()?;

let decrypted = {
    let decryptor = match age::Decryptor::new(
        age::armor::ArmoredReader::new(&encrypted[..])
    )? {
        age::Decryptor::Recipients(d) => d,
        _ => unreachable!(),
    };

    let mut decrypted = vec![];
    let mut reader = decryptor.decrypt(iter::once(&identity as &dyn age::Identity))?;
    reader.read_to_end(&mut decrypted);

    decrypted
};

Trait Implementations

impl<R: AsyncBufRead + Unpin> AsyncBufRead for ArmoredReader<R>

Available on crate features armor and async only.

fn poll_fill_buf( self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Result<&[u8]>>

Attempt to return the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(self: Pin<&mut Self>, amt: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to poll_read.

impl<R: AsyncBufRead + Unpin> AsyncRead for ArmoredReader<R>

Available on crate features armor and async only.

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut [u8] ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>] ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl<R: BufRead> BufRead for ArmoredReader<R>

Available on crate feature armor only.

fn fill_buf(&mut self) -> Result<&[u8]>

Returns the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

Read all bytes into buf until the delimiter byte or EOF is reached.

fn skip_until(&mut self, byte: u8) -> Result<usize, Error>

fn read_line(&mut self, buf: &mut String) -> Result<usize, Error>

fn split(self, byte: u8) -> Split<Self>

where Self: Sized,

Returns an iterator over the contents of this reader split on the byte byte.

fn lines(self) -> Lines<Self>

where Self: Sized,

Returns an iterator over the lines of this reader.

impl<R: BufRead> Read for ArmoredReader<R>

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)
