Fail-closed client-contract validation or codec error.

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.

InvalidVersion

Wire versions must be positive.

InvalidRequestId

Request identifiers must satisfy the bounded token grammar.

InvalidIdempotencyKey

Mutation replay keys must satisfy the bounded token grammar.

InvalidFailureCode

Failure codes must use the stable dotted grammar.

EmptyVersionOffer

A negotiation offer contained no version.

TooManyOfferedVersions

A negotiation offer exceeded its structural bound.

InvalidPolicy

Server policy range or body limit is invalid.

NoMutualVersion

Client and server share no supported version.

UnsupportedVersion

A request or response selected a version outside server policy.

Fields

received: u16

Received version.

minimum: u16

Minimum supported version.

current: u16

Latest supported version.

MissingIdempotencyKey

A state-changing request omitted its replay key.

BodyTooLarge

Encoded content exceeded the policy ceiling.

Fields

maximum: usize

Configured maximum size.

InvalidJson(Error)

Incoming JSON did not satisfy the typed envelope.

EncodeJson(Error)

A typed response could not be serialized.

Trait Implementations

impl Debug for ClientContractError

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

Formats the value using the given formatter.

impl Display for ClientContractError

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

Formats the value using the given formatter.

impl Error for ClientContractError

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.
