Enum BackendCreationError 

pub enum BackendCreationError {
    ConnectTimeoutTooLarge(Duration),
    FirstByteTimeoutTooLarge(Duration),
    BetweenBytesTimeoutTooLarge(Duration),
    Disallowed,
    HostError(FastlyStatus),
    EncodingError(FromUtf8Error),
    NameTooLong(String),
    NameInUse,
}

Errors that can arise from attempting to create a dynamic backend.

Perhaps the most critical of these is Disallowed, which will occur if your service is not permitted to use dynamic backends.

Variants

ConnectTimeoutTooLarge(Duration)

Timeouts for backends must be less than 2^32 milliseconds, or about a month and a half.

FirstByteTimeoutTooLarge(Duration)

Timeouts for backends must be less than 2^32 milliseconds, or about a month and a half.

BetweenBytesTimeoutTooLarge(Duration)

Timeouts for backends must be less than 2^32 milliseconds, or about a month and a half.

Disallowed

This service is not allowed to create dynamic backends.

If you’d like to use dynamic backends, please contact your Fastly sales agent.

HostError(FastlyStatus)

Something internal went wrong with the service at runtime; you may be able to do something to react to this information.

This value is identical to the values underlying FastlyStatus.

EncodingError(FromUtf8Error)

There was a problem converting the new name from the host into something we could turn into a Rust String.

Please check the prefix you provided, if you provided one, and make sure it’s reasonable.

NameTooLong(String)

The backend name provided was too long; please keep it to <255 characters.

NameInUse

The backend name is already in use.

Trait Implementations

impl Clone for BackendCreationError

fn clone(&self) -> BackendCreationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendCreationError

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

Formats the value using the given formatter.

impl Display for BackendCreationError

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

Formats the value using the given formatter.

impl Error for BackendCreationError

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<FastlyStatus> for BackendCreationError

fn from(x: FastlyStatus) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for BackendCreationError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.

impl PartialEq for BackendCreationError

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