ExitCode

Struct ExitCode 

Source
pub struct ExitCode(/* private fields */);
Expand description

CLI exit code with semantic meaning.

Provides type-safe exit codes following Unix conventions. Success is 0, errors are non-zero with specific meanings.

§Examples

use mcp_execution_core::cli::ExitCode;

let code = ExitCode::SUCCESS;
assert_eq!(code.as_i32(), 0);
assert!(code.is_success());

let code = ExitCode::from_i32(1);
assert!(!code.is_success());

Implementations§

Source§

impl ExitCode

Source

pub const SUCCESS: Self

Successful execution (exit code 0).

Source

pub const ERROR: Self

General error (exit code 1).

Source

pub const INVALID_INPUT: Self

Invalid input or arguments (exit code 2).

Source

pub const SERVER_ERROR: Self

Server connection or communication error (exit code 3).

Source

pub const TIMEOUT: Self

Execution timeout or resource limit exceeded (exit code 4).

Source

pub const fn from_i32(code: i32) -> Self

Creates an exit code from an integer value.

§Examples
use mcp_execution_core::cli::ExitCode;

let code = ExitCode::from_i32(0);
assert_eq!(code, ExitCode::SUCCESS);
Source

pub const fn as_i32(&self) -> i32

Returns the exit code as an integer.

§Examples
use mcp_execution_core::cli::ExitCode;

assert_eq!(ExitCode::SUCCESS.as_i32(), 0);
assert_eq!(ExitCode::ERROR.as_i32(), 1);
Source

pub const fn is_success(&self) -> bool

Checks if the exit code represents success.

§Examples
use mcp_execution_core::cli::ExitCode;

assert!(ExitCode::SUCCESS.is_success());
assert!(!ExitCode::ERROR.is_success());
