[−][src]Struct lzzzz::lz4f::AsyncWriteCompressor
This is supported on
feature="tokio-io"
only.The AsyncWrite
-based streaming compressor.
Example
use lzzzz::lz4f::AsyncWriteCompressor; use tokio::{fs::File, prelude::*}; let mut f = File::create("foo.lz4").await?; let mut w = AsyncWriteCompressor::new(&mut f, Default::default())?; w.write_all(b"Hello world!").await?; // You have to call shutdown() to finalize the frame. w.shutdown().await?;
