Enum oc_wasm_safe::component::MethodCallError

pub enum MethodCallError<'invoker> {
    CborDecode,
    BufferTooShort,
    NoSuchComponent,
    NoSuchMethod,
    BadParameters(LastException<'invoker>),
    QueueFull,

    Other(LastException<'invoker>),
    Unknown,
}

The possible errors that could occur during a method call.

Some errors carry additional information. This information is only available until the start of the next method call. The 'invoker lifetime ensures that the invoker cannot be reused to start another method call until a value of this type is dropped and therefore the additional error information is no longer accessible.

Implementations

impl<'invoker> MethodCallError<'invoker>

pub fn as_str(self) -> &'static str

Returns a string describing the error.

pub fn simplify(self) -> Error

Throws away the additional error information.

Trait Implementations

impl<'invoker> Clone for MethodCallError<'invoker>

fn clone(&self) -> MethodCallError<'invoker>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'invoker> Debug for MethodCallError<'invoker>

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

Formats the value using the given formatter.

impl Display for MethodCallError<'_>

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

Formats the value using the given formatter.

impl Error for MethodCallError<'_>

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

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<MethodCallError<'_>> for Error

fn from(source: MethodCallError<'_>) -> Self

Converts to this type from the input type.

impl<'invoker> Hash for MethodCallError<'invoker>

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<'invoker> PartialEq for MethodCallError<'invoker>

fn eq(&self, other: &MethodCallError<'invoker>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<Error> for MethodCallError<'static>

type Error = ()

The type returned in the event of a conversion error.

fn try_from(source: Error) -> Result<Self, Self::Error>

Performs the conversion.
