Variants

Config(String)

CachePoisoned

Compile(String)

Instantiate(String)

Fuel(String)

MissingExport(String)

OutOfFuel

EpochInterrupt

NoConversion(String)

ConvertCommodity raises this when no Price row links source and target in either direction. Lifted into a dedicated variant so clients can prompt the user to add a price row rather than guess from a generic trap message.

ScriptRaised

A structured error raised in-guest, surfaced via the __nomi_raise host fn (Err(wasmtime::Error::msg("__nomi_raise:CODE:MSG"))). Two sources converge here (ADR-0026): a script (error 'code "msg"), and an engine error like a commodity mismatch — both throw $nomi_error in-guest, and the boundary wrapper around each host-invoked body catches an uncaught throw and bridges it to __nomi_raise. The classifier parses the marker prefix and surfaces the code symbol (COMMODITY-MISMATCH, a script’s own symbol, …) onto the wire envelope’s :code slot. Codes are reader-folded (upper-cased) symbols, not free-form strings.

Fields

code: String

message: String

Trap(String)

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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<EngineError> for SessionError

fn from(source: EngineError) -> Self

Converts to this type from the input type.
