[−][src]Struct buf_ref_reader::BufRefReader

pub struct BufRefReader<R, B> { /* fields omitted */ }

Buffering reader.

See module-level docs for examples.

Methods

impl<R: Read, B: Buffer> BufRefReader<R, B> where
    Error: From<B::Error>, [src]

pub fn new(src: R) -> Result<BufRefReader<R, B>, B::Error>[src]

Creates buffered reader with default options. Look for BufRefReaderBuilder for tweaks.

pub fn read(&mut self, n: usize) -> Result<Option<&[u8]>, Error>[src]

Returns requested amount of bytes, or less if EOF prevents reader from fulfilling the request.

Returns:

  • Ok(Some(data)) with, well, data,
  • Ok(None) if no more data is available,
  • Err(err): see std::io::Read::read()

pub fn read_until(&mut self, delim: u8) -> Result<Option<&[u8]>, Error>[src]

Returns bytes up until and including delim, or until EOF mark. If no content is available, returns None.

Returns:

  • Ok(Some(data)) with, well, data,
  • Ok(None) if no more data is available,
  • Err(err): see std::io::Read::read()
