Struct nix_compat::nar::reader::async::FileReader

pub struct FileReader<'a, 'r> {
    inner: BytesReader<&'a mut Reader<'r>, PadPar>,
}

File contents, readable through the AsyncRead trait.

It comes with some caveats:

• You must always read the entire file, unless you intend to abandon the entire archive reader.
• You must abandon the entire archive reader upon the first error.

It’s fine to read exactly reader.len() bytes without ever seeing an explicit EOF.

Fields

inner: BytesReader<&'a mut Reader<'r>, PadPar>

Implementations

impl<'a, 'r> FileReader<'a, 'r>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> u64

Trait Implementations

impl<'a, 'r> AsyncBufRead for FileReader<'a, 'r>

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

Attempts 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<'a, 'r> AsyncRead for FileReader<'a, 'r>

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut ReadBuf<'_>, ) -> Poll<Result<()>>

Attempts to read from the AsyncRead into buf.
