Protocol error vocabulary. #[non_exhaustive]: downstream matches must carry a wildcard arm so new error variants are not a breaking change.

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.

InvalidMacpVersion

InvalidEnvelope

SessionAlreadyExists

UnknownSession

SessionNotOpen

TtlExpired

InvalidTtl

UnknownMode

InvalidModeState

InvalidPayload

Forbidden

Unauthenticated

DuplicateMessage

Kept for RFC error-code completeness. The runtime currently represents duplicate detection via ProcessResult { duplicate: true } at the Ack level rather than returning this as an error.

PayloadTooLarge

RateLimited

StorageFailed

InvalidSessionId

UnknownPolicyVersion

PolicyDenied

Fields

reasons: Vec<String>

InvalidPolicyDefinition

Implementations

impl MacpError

pub fn error_code(&self) -> &'static str

Returns the RFC error code string for this error variant.

Trait Implementations

impl Debug for MacpError

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

Formats the value using the given formatter.

impl Display for MacpError

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

Formats the value using the given formatter.

impl Error for MacpError

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.
