Module cli 

CLI-specific types and utilities.

This module provides strong types for CLI concepts following Microsoft Rust Guidelines, ensuring type safety and clear intent throughout the CLI codebase.

Design Principles

• Strong types over primitives (no raw strings/ints for domain concepts)
• All types are Send + Sync + Debug
• Validation at construction boundaries
• User-friendly error messages

Examples

use mcp_execution_core::cli::{OutputFormat, ExitCode, ServerConnectionString};
use std::path::PathBuf;

// Output format selection
let format = OutputFormat::Pretty;
assert_eq!(format.as_str(), "pretty");

// Exit codes with semantic meaning
let code = ExitCode::SUCCESS;
assert_eq!(code.as_i32(), 0);

// Validated server connection strings
let conn = ServerConnectionString::new("github").unwrap();
assert_eq!(conn.as_str(), "github");

Structs

CLI exit code with semantic meaning.
