Enum ExtError

#[non_exhaustive]
pub enum ExtError {
    Execution(ExecutionError),
    Memory(MemoryError),
    Message(MessageError),
    Reservation(ReservationError),
    Unsupported,
}

An error occurred in API.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Execution(ExecutionError)

Execution error.

Memory(MemoryError)

Memory error.

Message(MessageError)

Message error.

Reservation(ReservationError)

Reservation error.

Unsupported

There is a new error variant old program don’t support.

Implementations

impl ExtError

pub fn to_u32(self) -> u32

Convert error into code.

pub fn from_u32(code: u32) -> Option<Self>

Convert code into error.

Trait Implementations

impl Clone for ExtError

fn clone(&self) -> ExtError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtError

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

Formats the value using the given formatter.

impl Display for ExtError

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

Formats the value using the given formatter.

impl Error for ExtError

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 From<ExecutionError> for ExtError

fn from(source: ExecutionError) -> Self

Converts to this type from the input type.

impl From<MemoryError> for ExtError

fn from(source: MemoryError) -> Self

Converts to this type from the input type.

impl From<MessageError> for ExtError

fn from(source: MessageError) -> Self

Converts to this type from the input type.

impl From<ReservationError> for ExtError

fn from(source: ReservationError) -> Self

Converts to this type from the input type.

impl Hash for ExtError

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 ExtError

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

impl Sequence for ExtError

const CARDINALITY: usize = 31usize

Number of values of type Self.

fn next(&self) -> Option<Self>

Returns value following *self or None if this was the end.

fn previous(&self) -> Option<Self>

Returns value preceding *self or None if this was the beginning.

fn first() -> Option<Self>

Returns the first value of type Self.

fn last() -> Option<Self>

Returns the last value of type Self.
