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.

BufferLengthError

Thrown by hostcalls when a buffer is larger than its *_len limit.

Fields

buf: &'static str

len: &'static str

FatalError(String)

Error when viceroy has encountered a fatal error and the underlying wasmtime instance must be terminated with a Trap.

FileFormat

Error when viceroy has been given an invalid file.

ProfilingStrategy

FastlyConfig(FastlyConfigError)

BackendUrl(Url)

GuestError(GuestError)

An error from guest-provided arguments to a hostcall. These errors may be created automatically by the Wiggle-generated glue code that converts parameters from their ABI representation into richer Rust types, or by fallible methods of GuestPtr in the wiggle_abi trait implementations.

HandleError(HandleError)

HyperError(Error)

Infallible(Infallible)

InvalidArgument

Error when an invalid argument is supplied to a hostcall.

InvalidHeaderName(InvalidHeaderName)

InvalidHeaderValue(InvalidHeaderValue)

InvalidMethod(InvalidMethod)

InvalidStatusCode(InvalidStatusCode)

InvalidUri(InvalidUri)

IoError(Error)

Other(Error)

Unsupported

Fields

msg: &'static str

DownstreamRespSending

Downstream response is already sending.

StreamingChunkSend

UnknownBackend(String)

DictionaryError(DictionaryError)

DeviceDetectionError(DeviceDetectionError)

KvStoreError(KvStoreError)

SecretStoreError(SecretStoreError)

Utf8Expected(Utf8Error)

NotAvailable(&'static str)

Implementations

impl Error

pub fn to_fastly_status(&self) -> FastlyStatus

Convert to an error code representation suitable for passing across the ABI boundary.

For more information about specific error codes see fastly_shared::FastlyStatus, as well as the witx interface definition located in wasm_abi/typenames.witx.

Trait Implementations

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
