Errors produced by wrap_component.

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.

WitParse

The supplied WIT string failed to parse via wit-parser. Should not happen for strings produced by crate::emit_wit, which round-trips its own output before returning.

Fields

reason: String

wit-parser’s diagnostic rendered as a string.

WorldMissing

The supplied WIT did not declare a world named crate::wit::WORLD_NAME.

Fields

reason: String

wit-parser’s diagnostic rendered as a string.

EmbedFailed

wit_component::embed_component_metadata failed to attach the custom section to the core module.

Fields

reason: String

wit-component’s diagnostic rendered as a string.

EncoderRejected

ComponentEncoder::module rejected the core-Wasm bytes — most likely because the embedded metadata refers to exports the module does not actually provide.

Fields

reason: String

wit-component’s diagnostic rendered as a string.

EncodeFailed

ComponentEncoder::encode produced no bytes — the encoder ran to completion but the result failed component-model validation.

Fields

reason: String

wit-component’s diagnostic rendered as a string.

Trait Implementations

impl Debug for ComponentWrapError

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

Formats the value using the given formatter.

impl Display for ComponentWrapError

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

Formats the value using the given formatter.

impl Error for ComponentWrapError

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<ComponentWrapError> for WasmBackendError

fn from(source: ComponentWrapError) -> Self

Converts to this type from the input type.
