Enum ControlError 

pub enum ControlError {
    UnknownRequest(i32),
    InvalidParameter,
}

Error type for the control functions of the encoder and decoder.

Variants

UnknownRequest(i32)

The request type passed to the control function was invalid The parameter is the request type that was passed

InvalidParameter

The parameter passed to the control function was invalid (and probably caused a segfault, making this error unreachable)

Trait Implementations

impl Clone for ControlError

fn clone(&self) -> ControlError

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, f: &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: &ControlError) -> 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.
