Struct zstd::stream::raw::Encoder

source ·
pub struct Encoder<'a> { /* private fields */ }
Expand description

An in-memory encoder for streams of data.

Implementations§

source§

impl Encoder<'static>

source

pub fn new(level: i32) -> Result<Self>

Creates a new encoder.

source

pub fn with_dictionary(level: i32, dictionary: &[u8]) -> Result<Self>

Creates a new encoder initialized with the given dictionary.

source§

impl<'a> Encoder<'a>

source

pub fn with_prepared_dictionary<'b>( dictionary: &EncoderDictionary<'b> ) -> Result<Self>where 'b: 'a,

Creates a new encoder using an existing EncoderDictionary.

source

pub fn set_parameter(&mut self, parameter: CParameter) -> Result<()>

Sets a compression parameter for this encoder.

source

pub fn set_pledged_src_size( &mut self, pledged_src_size: Option<u64> ) -> Result<()>

Sets the size of the input expected by zstd.

May affect compression ratio.

It is an error to give an incorrect size (an error will be returned when closing the stream).

If None is given, it assume the size is not known (default behaviour).
