Enum WasmDispatchError 

pub enum WasmDispatchError {
    Incompatible {
        decision: WasmAbiCompatibilityDecision,
    },
    Handle(WasmHandleError),
    InvalidState {
        state: WasmBoundaryState,
        symbol: WasmAbiSymbol,
    },
    InvalidRequest {
        reason: String,
    },
}

Error returned when a dispatch call fails at the boundary level (before reaching the runtime).

Variants

Incompatible

ABI version is not compatible.

Fields

decision: WasmAbiCompatibilityDecision

The compatibility decision that rejected the call.

Handle(WasmHandleError)

Handle validation failed.

InvalidState

Boundary state does not allow this operation.

Fields

state: WasmBoundaryState

Current boundary state.

symbol: WasmAbiSymbol

Attempted operation.

InvalidRequest

Request payload failed validation.

Fields

reason: String

Explanation of the validation failure.

Implementations

impl WasmDispatchError

pub fn to_failure(&self) -> WasmAbiFailure

Converts this dispatch error to a boundary failure envelope.

pub fn to_outcome(&self) -> WasmAbiOutcomeEnvelope

Wraps this error as an Err outcome envelope.

Trait Implementations

impl Clone for WasmDispatchError

fn clone(&self) -> WasmDispatchError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmDispatchError

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

Formats the value using the given formatter.

impl Display for WasmDispatchError

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

Formats the value using the given formatter.

impl Error for WasmDispatchError

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<WasmHandleError> for WasmDispatchError

fn from(source: WasmHandleError) -> Self

Converts to this type from the input type.

impl PartialEq for WasmDispatchError

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