Struct zstd::block::Compressor
[−]
[src]
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[src]
fn new() -> Self[src]
Creates a new zstd compressor
fn with_dict(dict: Vec<u8>) -> Self[src]
Creates a new zstd compressor, using the given dictionary.
fn compress_to_buffer(
&mut self,
source: &[u8],
destination: &mut [u8],
level: i32
) -> Result<usize>[src]
&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).
fn compress(&mut self, data: &[u8], level: i32) -> Result<Vec<u8>>[src]
Compresses a block of data and returns the compressed result.
A level of 0 uses zstd's default (currently 3).
