tg-signal

Signal handling abstractions for the rCore tutorial operating system.

Overview

This crate defines the Signal trait and related types for Unix-like signal handling in the rCore tutorial kernel. It provides the interface that signal implementations must follow.

Features

• Signal trait: Abstract interface for signal management
• SignalResult: Enumeration of possible signal handling outcomes
• Standard signal support: Re-exports signal definitions from tg-signal-defs
• no_std compatible: Designed for bare-metal kernel environments

Usage

use tg_signal::{Signal, SignalAction, SignalNo, SignalResult};

// Implement the Signal trait for your signal handler
impl Signal for MySignalHandler {
    fn from_fork(&mut self) -> Box<dyn Signal> { /* ... */ }
    fn add_signal(&mut self, signal: SignalNo) { /* ... */ }
    fn handle_signals(&mut self, ctx: &mut LocalContext) -> SignalResult { /* ... */ }
    // ... other methods
}

Core Types

• Signal - Trait defining the signal handling interface
• SignalResult - Result type for signal handling operations (NoSignal, Handled, ProcessKilled, etc.)
• SignalAction - Signal handler configuration structure
• SignalNo - Signal number enumeration

Related Crates

• tg-signal-defs - Signal number and action definitions
• tg-signal-impl - A concrete implementation of the Signal trait
