Struct ExitCode 

pub struct ExitCode(/* private fields */);

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

impl ExitCode

pub const SUCCESS: Self

Successful execution (exit code 0).

pub const ERROR: Self

General error (exit code 1).

pub const INVALID_INPUT: Self

Invalid input or arguments (exit code 2).

pub const SERVER_ERROR: Self

Server connection or communication error (exit code 3).

pub const TIMEOUT: Self

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

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);

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);

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());

Trait Implementations

impl Clone for ExitCode

fn clone(&self) -> ExitCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExitCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ExitCode

fn default() -> Self

Returns the “default value” for a type.

impl Display for ExitCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ExitCode> for i32

fn from(code: ExitCode) -> Self

Converts to this type from the input type.

impl Hash for ExitCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ExitCode

fn eq(&self, other: &ExitCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
