Module shared 

Shared module for code reuse between bssh client and server.

This module contains utilities and types that are used by both the bssh SSH client and the bssh-server implementations. By centralizing this shared code, we ensure:

• Consistent behavior between client and server
• No code duplication
• Easier maintenance

Modules

• validation: Input validation utilities for usernames, hostnames, paths
• rate_limit: Generic token bucket rate limiter
• auth_types: Common authentication types and results
• error: Shared error types

Usage

The shared module is designed to be used transparently by other modules. For backward compatibility, the existing modules (security, jump) re-export these shared utilities, so existing code continues to work.

Direct Usage

use bssh::shared::validation::validate_hostname;
use bssh::shared::rate_limit::RateLimiter;
use bssh::shared::auth_types::{AuthResult, UserInfo};

// Validate a hostname
let hostname = validate_hostname("example.com").unwrap();

// Use the generic rate limiter
let limiter: RateLimiter<String> = RateLimiter::new();

Via Re-exports (Backward Compatible)

// These continue to work as before
use bssh::security::validate_hostname;
use bssh::jump::rate_limiter::ConnectionRateLimiter;
