Struct zstd::block::Compressor

[+] Show declaration

pub struct Compressor { /* fields omitted */ }

[−] Expand description

Allows to compress independently multiple blocks of data.

This reduces memory usage compared to calling compress multiple times. The compressed blocks are still completely independent.

Implementations

impl Compressor[−]

pub fn new() -> Self[−]

Creates a new zstd compressor

pub fn with_dict(dict: Vec<u8>) -> Self[−]

Creates a new zstd compressor, using the given dictionary.

pub fn compress_to_buffer(
    &mut self,
    source: &[u8],
    destination: &mut [u8],
    level: i32
) -> Result<usize>[−]

Compress a single block of data to the given destination buffer.

Returns the number of bytes written, or an error if something happened (for instance if the destination buffer was too small).

A level of 0 uses zstd’s default (currently 3).

pub fn compress(&mut self, data: &[u8], level: i32) -> Result<Vec<u8>>[−]

Compresses a block of data and returns the compressed result.

A level of 0 uses zstd’s default (currently 3).
