Crate async_deflate_zip 

Streaming async ZIP archive writer with per-file deflate compression.

This crate provides an asynchronous interface for creating ZIP archives from streams of data. Unlike blocking ZIP writers, entries are written incrementally — each file is compressed and written to the output as it arrives, without buffering the entire archive in memory.

Architecture

The crate is organized into three modules:

• ZipWriter — Streaming ZipWriter and per-entry EntryWriter
• Compression — Deflate compression level (0-9) (re-exported from flate2)

Quick Start

use async_deflate_zip::ZipWriter;
use tokio::io::AsyncWriteExt;

let mut buf = Vec::new();
let mut zip = ZipWriter::new(&mut buf);

let mut entry = zip.append_file("hello.txt").await.unwrap();
entry.write_all(b"Hello, World!").await.unwrap();
entry.close().await.unwrap();

zip.finalize().await.unwrap();

Structs

Compression

When compressing data, the compression level can be specified by a value in this struct.

DirectoryWriter

A handle for finalizing a directory entry in a ZIP archive.

EntryWriter

A streaming writer for a single file entry in a ZIP archive.

ZipWriter

A streaming ZIP archive writer with per-file deflate compression.

Enums

ZipError

Errors that can occur when creating a ZIP archive.
