//! A minimal RISC-V's SBI implementation in Rust.
//!
//! This library adapts to embedded Rust's `embedded-hal` crate to provide basical SBI features. 
//! When building for own platform, implement traits in this library and pass them to the functions
//! begin with `init`. After that, you may call `rustsbi::ecall` in your own exception handler
//! which would dispatch parameters from supervisor to the traits to execute SBI functions.
//!
//! The library also implements useful functions which may help with platform specific binaries.
//! The `enter_privileged` maybe used to enter the operating system after the initialization 
//! process is finished. The `LOGO` should be printed if necessary when the binary is initializing.
//! 
//! Note that this crate is a library which contains common building blocks in SBI implementation.
//! It is not intended to be used directly; users should build own platforms with this library.
//! RustSBI provides implementations on common platforms in separate platform crates.
