Struct HuffmanWriter

pub struct HuffmanWriter<W>
where
    W: Write,
{ /* private fields */ }

HuffmanWriter is a Write implementation that writes encoded words to the inner writer.

Examples

extern crate huffman_coding;
let pseudo_data = vec![0, 0, 1, 2, 2];
let tree = huffman_coding::HuffmanTree::from_data(&pseudo_data[..]);

let mut output = Vec::new();
{
    use std::io::Write;
    let mut writer = huffman_coding::HuffmanWriter::new(&mut output, &tree);
    assert!(writer.write(&[2, 2, 0, 0, 1]).is_ok());
}
assert_eq!(&output[..], [43, 8]);

Implementations

impl<W> HuffmanWriter<W>

where W: Write,

pub fn new(writer: W, tree: &HuffmanTree) -> Self

Construct a new HuffmanWriter using the provided HuffmanTree

Trait Implementations

impl<W> Write for HuffmanWriter<W>

where W: Write,

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

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> IOResult<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

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

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

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

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
