Struct huffman_coding::HuffmanWriter

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

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]);

Methods

impl<W> HuffmanWriter<W> where
    W: Write, 

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>

Write a buffer into this object, returning how many bytes were written.

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

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

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

Attempts to write an entire buffer into this write.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

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

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

Creates a "by reference" adaptor for this instance of Write.
