Enum CommandResult 

pub enum CommandResult {
    Success,
    Error(String),
}

Result of command execution.

Like Unix exit codes: commands return status only. Side effects go through runtime.signal().

Variants

Success

Command executed successfully (exit code 0).

Error(String)

Command failed with an error message (non-zero exit).

Implementations

impl CommandResult

pub const fn is_success(&self) -> bool

Check if the result is success.

pub const fn is_error(&self) -> bool

Check if the result is an error.

pub fn error(msg: &str) -> CommandResult

Create an error result with a message.

Trait Implementations

impl Clone for CommandResult

fn clone(&self) -> CommandResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommandResult

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

Formats the value using the given formatter.

impl PartialEq for CommandResult

fn eq(&self, other: &CommandResult) -> 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.
