autocompress-rs

Automatically select suitable decoder from magic bytes or encoder from file extension. This library also provides I/O thread pool to perform decompression and compression in background threads.

Supported file formats

• Gzip
• Zlib (Cannot suggest format from magic bytes and file extension)
• BZip2
• XZ
• Snappy (Cannot suggest format from file extension)
• Z-standard
• LZ4
• Brotli (Cannot suggest format from magic bytes)

Feature flags

• default, full: Enable all features.
• gzip: Enable gzip
• snap: Enable snappy
• zstd: Enable Z-standard
• bzip2: Enable bzip2
• lz4: Enable LZ4
• xz: Enable XZ
• brotli: Enable Brotli
• thread: Enable threaded I/O

Example

```rust use autocompress::open; use std::io::{self, Read};

fn main() -> io::Result<()> { let mut buffer = Vec::new(); open("testfiles/plain.txt.xz")?.readtoend(&mut buffer)?; assert_eq!(buffer, b"ABCDEFG\r\n1234567"); Ok(()) } ```

I/O thread example

rust use autocompress::{iothread::IoThread, open, create, CompressionLevel}; use std::io::{prelude::*, self}; fn main() -> io::Result<()> { let thread_pool = IoThread::new(2); let mut threaded_reader = thread_pool.open("testfiles/plain.txt.xz")?; let mut threaded_writer = thread_pool.create("target/plain.txt.xz", CompressionLevel::Default)?; let mut buffer = Vec::new(); threaded_reader.read_to_end(&mut buffer)?; assert_eq!(buffer, b"ABCDEFG\r\n1234567"); threaded_writer.write_all(b"ABCDEFG\r\n1234567")?; Ok(()) }
