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

An encoder that compress input data from another Read.

Implementations

Creates a new encoder.

Creates a new encoder around a BufRead.

Creates a new encoder, using an existing dictionary.

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

Creates a new encoder, using an existing EncoderDictionary.

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 encoder 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 the given zstd compression parameter.

Sets the expected size of the input.

This affects the compression effectiveness.

It is an error to give an incorrect size (an error will be returned when closing the stream if the size does not match what was pledged).

Giving a None size means the size is unknown (this is the default).

Controls whether zstd should include a content checksum at the end of each frame.

Enables or disables storing of the dict id.

Defaults to true. If false, the behaviour of decoding with a wrong dictionary is undefined.

Enables or disabled storing of the contentsize.

Note that this only has an effect if the size is given with set_pledged_src_size.

Enables or disables long-distance matching

Sets the maximum back-reference distance.

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

Note that decompression will need to use at least the same setting.
