Module shell 

Interactive shell subsystem for oveRTOS.

Provides init, process_char, and register_cmd for building a simple command-line interface over a serial console. Commands are registered as safe Rust fn(args: &[&[u8]]) callbacks; the FFI trampoline handles the C/Rust boundary automatically.

process_char

Process a single input character through the shell.

process_line

Process a complete input line through the shell.

register_cmd

Register a shell command with a safe Rust handler.

set_output_hook

Type Aliases
