Struct zstd::block::Compressor

pub struct Compressor { /* fields omitted */ }

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.

Methods

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).

Trait Implementations

impl Default for Compressor

fn default() -> Compressor

Returns the "default value" for a type.
