Implementations

impl WasmError

pub fn classify_trap(trap: &Trap) -> TrapReason

Classify a wasmtime Trap into a TrapReason.

Uses the trap type for well-known cases and falls back to message matching for epoch-related traps.

Note: wasmtime::Trap is #[non_exhaustive] — the other catch-all arm is required and handles any future trap variants added by wasmtime.

pub fn plugin_name(&self) -> Option<&str>

Returns the plugin name associated with this error, if any.

Trait Implementations

impl Clone for WasmError

fn clone(&self) -> WasmError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmError

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

Formats the value using the given formatter.

impl Display for WasmError

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

Formats the value using the given formatter.

impl Error for WasmError

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<Error> for WasmError

? ergonomics for the bindgen trappable layer: when a generated call_*(...) returns Result<_, wasmtime::Error> (the trappable wrapper around a WIT result<_, _>), this impl lets ? convert the trap to the canonical WasmError::GuestPanic (further classified later via classify_error if more precision is needed).

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<WasmError> for CamelError

fn from(err: WasmError) -> Self

Converts to this type from the input type.
