//! Trussed® is a minimal, modular way to write cryptographic applications on microcontroller platforms.
//! Easy to write, easy to audit — compile-time security by default.
//!
//! Documentation is evolving, a good entry point is the module `trussed::client`.

// prevent a spurious error message: https://github.com/rust-lang/rust/issues/54010
// UNFORTUNATELY: with #![cfg(test)], no longer compiles for no_std,
// with #[cfg(test)] error still shown
// #[cfg(test)]

// Temporarily disabled until documentation coverage is improved.
