Enum ControlError 

pub enum ControlError {
    Io(String),
    Key(String),
    Unauthorized,
    Protocol(String),
    Remote {
        error: String,
        detail: Option<Value>,
    },
}

Why a control-port operation failed.

Variants

Io(String)

Binding, connecting, reading or writing failed.

Key(String)

The key could not be made, written or read.

Unauthorized

The app refused the key (it restarted with a new one, or this is someone else’s port).

Protocol(String)

The peer did not speak the protocol.

Remote

The app answered with an error.

Fields

error: String

detail: Option<Value>

Implementations

impl ControlError

pub fn into_command_error(self, id: &str) -> CommandError

As a CommandError: the app’s own when it sent one, otherwise CommandError::Failed.

Trait Implementations

impl Clone for ControlError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ControlError

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

Formats the value using the given formatter.

impl Display for ControlError

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

Formats the value using the given formatter.

impl Error for ControlError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ControlError

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

Equality operator ==.

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

Inequality operator !=.
