15//! This crate provides stubs for parts of the applet API.
16//!
17//! By default, when using the applet API with the `native` feature, all calls to the applet API
18//! will panic. This crate provides a working implementation for some parts of the API (like the
19//! crypto module).
20//!
21//! Note that this crate doesn't expose anything. To use it, you just need to link it:
22//!
23//! ```
24//! use wasefire_stub as _;
25//! ```
