Struct zstd::stream::read::Decoder[][src]

pub struct Decoder<'a, R: BufRead> { /* fields omitted */ }
Expand description

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).

Implementations

Creates a new decoder.

Creates a new decoder around a BufRead.

Creates a new decoder, using an existing dictionary.

The dictionary must be the same as the one used during compression.

Sets this Decoder to stop after the first frame.

By default, it keeps concatenating frames until EOF is reached.

Creates a new decoder, using an existing DecoderDictionary.

The dictionary must be the same as the one used during compression.

Recommendation for the size of the output buffer.

Acquire a reference to the underlying reader.

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.

Return the inner Read.

Calling finish() is not required after reading a stream - just use it if you need to get the Read back.

Sets a decompression parameter on the decompression stream.

Sets the maximum back-reference distance.

The actual maximum distance is going to be 2^log_distance.

Enables or disabled expecting the 4-byte magic header

Only available with the experimental feature.
