//! Asynchronous parser and writer for Electron's asar archive format.

//! Currently supported:
//! - Parse archive from file or async reader
//! - Pack archive from multiple readers, or conveniently from a folder.
//!
//! Currently not supported:
//! - Write and check integrity (planned)
//! - Unpacked files (planned)
//! - [`FileMetadata::executable`](header::FileMetadata::executable) (not
//!   planned, it is up to you whether use it or not)
