Struct ZstdCompressStream 

pub struct ZstdCompressStream<'s> { /* private fields */ }

Implementations

impl ZstdCompressStream<'_>

pub fn new(compression_level: i32, resize_by: usize) -> Result<Self, ZstdError>

Arguments

• compression_level - The compression level to use.
• resize_by - The amount to resize the buffer by when it runs out of space.

pub fn multithreaded(&mut self, workers: u8) -> Result<(), ZstdError>

Sets the number of worker threads to use for compression. Can be called at any time. Setting workers to >= 1 will make compression asynchronous. All compression will be done in background threads. So it’s important to call finish before dropping the stream.

pub fn write( &mut self, uncompressed: &[u8], compress_buffer: &mut Vec<u8>, ) -> Result<(), ZstdError>

pub fn finish(&mut self, compress_buffer: &mut Vec<u8>) -> Result<(), ZstdError>

pub fn reset(&mut self) -> Result<(), ZstdError>

Resets the compression context. You can again write data to the stream after calling this method.
