[−][src]Struct lzzzz::lz4f::AsyncBufReadDecompressor
This is supported on
feature="tokio-io"
only.The AsyncBufRead
-based streaming decompressor.
Example
use lzzzz::lz4f::AsyncBufReadDecompressor; use tokio::{fs::File, io::BufReader, prelude::*}; let mut f = File::open("foo.lz4").await?; let mut b = BufReader::new(f); let mut r = AsyncBufReadDecompressor::new(&mut b)?; let mut buf = Vec::new(); r.read_frame_info().await?; r.read_to_end(&mut buf).await?;
Implementations
impl<'a, R: AsyncBufRead + Unpin> AsyncBufReadDecompressor<'a, R>
[src]
pub fn new(reader: R) -> Result<Self>
[src]
Creates a new AsyncBufReadDecompressor<R>
.
pub fn set_dict<D>(&mut self, dict: D) where
D: Into<Cow<'a, [u8]>>,
[src]
D: Into<Cow<'a, [u8]>>,
Sets the dictionary.
pub async fn read_frame_info<'_>(&'_ mut self) -> Result<FrameInfo>
[src]
Reads the frame header asynchronously and returns FrameInfo
.
Calling this function before any AsyncRead
or AsyncBufRead
operations
does not consume the frame body.
