Module archive 

Async archive reader abstraction layer.

This module provides the AsyncArchiveReader trait, which defines the interface for asynchronously reading entries from archive containers (ZIP files). It mirrors the synchronous lib3mf_core::archive::ArchiveReader trait but with async methods.

Design

The trait abstracts over different async archive implementations, allowing the 3MF loader to work with any async archive backend. Currently, AsyncZipArchive is the primary implementation using the async-zip crate.

Examples

use lib3mf_async::archive::AsyncArchiveReader;
use lib3mf_async::zip::AsyncZipArchive;
use tokio::fs::File;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let file = File::open("model.3mf").await?;
    let mut archive = AsyncZipArchive::new(file).await?;

    // Check if an entry exists
    if archive.entry_exists("_rels/.rels").await {
        // Read the entry
        let data = archive.read_entry("_rels/.rels").await?;
        println!("Read {} bytes", data.len());
    }

    // List all entries
    let entries = archive.list_entries().await?;
    println!("Archive contains {} entries", entries.len());

    Ok(())
}
