Errors originating from WASM components.

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.

PortMissing(String)

Thrown when a user attempts to retrieve a stream for a port that doesn’t exist.

Decode

Error deserializing payload.

Fields

as_json: String

error: String

Jsonify(String)

Error converting payload into JSON.

Channel(String)

Error communicating over a stream or channel.

Component(String)

General error to wrap other errors.

NoData

Payload was successful but no data was provided.

PayloadError(PacketError)

An error that wraps a PayloadError.

UnexpectedDone

Thrown when a user attempts to use a signal when they expected a payload.

ContextKey(String)

Returned when an operation attempts to retrieve a configuration item that doesn’t exist or decoding fails.

BadJson(Value)

Returned when trying to decode a non-JSON object into crate::RuntimeConfig.

StreamMapError(String, String)

Couldn’t retrieve a complete set of packets from a crate::StreamMap

StreamMapMissing(String)

Couldn’t retrieve a complete set of packets from a crate::StreamMap

Signature(String, String)

Coersion

Fields

value: Value

desired: Type

Implementations

impl Error

pub fn component_error<T: Into<String>>(msg: T) -> Self

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Box<dyn Error>> for Error

fn from(value: Box<dyn Error>) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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