Struct zstd::stream::Decoder
[−]
[src]
pub struct Decoder<R: Read> { /* fields omitted */ }
A decoder that decompress input data from another Read.
This allows to read a stream of compressed data (good for files or heavy network stream).
Methods
impl<R: Read> Decoder<R>[src]
fn new(reader: R) -> Result<Self>[src]
Creates a new decoder.
fn single_frame(self) -> Self[src]
Sets this Decoder to stop after the first frame.
By default, it keeps concatenating frames until EOF is reached.
fn with_dictionary(reader: R, dictionary: &[u8]) -> Result<Self>[src]
Creates a new decoder, using an existing dictionary.
The dictionary must be the same as the one used during compression.
fn recommended_output_size() -> usize[src]
Recommendation for the size of the output buffer.
fn get_ref(&self) -> &R[src]
Acquire a reference to the underlying reader.
fn get_mut(&mut self) -> &mut R[src]
Acquire a mutable reference to the underlying reader.
Note that mutation of the reader may result in surprising results if this decoder is continued to be used.
fn finish(self) -> R[src]
Return the inner Read.
Calling finish() is not required after reading a stream -
just use it if you need to get the Read back.
