engram-rs 1.2.0

//! Engram-rs: Unified archive library with manifest, signatures, and VFS support
//!
//! This library provides a complete implementation of the Engram v0.3 archive format,
//! combining:
//! - Compressed archive storage (LZ4/Zstd)
//! - Manifest with signature verification
//! - VFS (Virtual File System) via embedded SQLite databases
//! - Fast O(1) file lookup
//!
//! # Example
//!
//! ```no_run
//! use engram_rs::{ArchiveWriter, ArchiveReader};
//!
//! // Create an archive
//! let mut writer = ArchiveWriter::create("example.eng")?;
//! writer.add_file("data.txt", b"Hello, World!")?;
//! writer.finalize()?;
//!
//! // Read from archive
//! let mut reader = ArchiveReader::open("example.eng")?;
//! let data = reader.read_file("data.txt")?;
//! # Ok::<(), engram_rs::error::EngramError>(())
//! ```
