Enum ErrorCode 

#[non_exhaustive]
pub enum ErrorCode {
    BadRequest,
    EnrollmentFailed,
    NotApproved,
    Forbidden,
    CertificateError,
    InternalError,
    SequenceError,
    Other(String),
}

Machine-readable error code sent in ErrorPayload.

Wire forward-compatibility

Other(String) is a catch-all for error codes received from a newer controller that this build does not yet recognise. Serde deserialization is infallible: an unknown string becomes Other(...) rather than a parse error, allowing older agents to survive rolling upgrades without dropping the enclosing Error message.

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.

BadRequest

Malformed or unexpected message from the service.

EnrollmentFailed

Enrollment attempt failed on the controller side.

NotApproved

Service is not approved (pending or rejected).

Forbidden

Service is not allowed to perform this action.

CertificateError

Certificate signing or renewal error.

InternalError

Unrecoverable server-side error.

SequenceError

Message sequence number mismatch (replay protection).

Other(String)

An unknown error code received from a newer peer.

The inner string is the raw snake_case value as it appeared on the wire.

Implementations

impl ErrorCode

pub fn as_str(&self) -> &str

Returns the string representation.

For ErrorCode::Other, returns the inner string as-is.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErrorCode

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Eq for ErrorCode

impl From<String> for ErrorCode

fn from(s: String) -> Self

Converts a snake_case string to an error code.

Unknown strings map to ErrorCode::Other rather than failing.

impl PartialEq for ErrorCode

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

impl Serialize for ErrorCode

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
