//! Rust libavb.
//!
//! This library wraps the libavb C code with safe Rust APIs. This does not materially affect the
//! safety of the library itself, since the internal implementation is still C. The goal here is
//! instead to provide a simple way to use libavb from Rust, in order to make Rust a more
//! appealing option for code that may want to use libavb such as bootloaders.
//!
//! This library is [no_std] for portability.
// ANDROID: Use std to allow building as a dylib.
// This condition lets us make the hack to add a dependency on std for the
// panic_handler and eh_personality conditional on actually building a dylib.
#![cfg_attr(not(any(test, android_dylib)), no_std)]
