Enum RegistrationError 

#[non_exhaustive]
pub enum RegistrationError {
    AlreadyRegistered,
    QuotaExceeded,
    NetworkError(NetworkError),
    LocalDataError(String),
}

Errors from remote registry operations.

Usage:

match register_result {
    Err(RegistrationError::AlreadyRegistered) => { /* skip */ }
    Err(RegistrationError::QuotaExceeded) => { /* retry later */ }
    Err(e) => return Err(e.into()),
    Ok(outcome) => { /* success */ }
}

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.

AlreadyRegistered

The identity is already registered at the target registry.

QuotaExceeded

The registration rate limit has been exceeded.

NetworkError(NetworkError)

A network error occurred during registration.

LocalDataError(String)

Local identity or attestation data is invalid.

Trait Implementations

impl Debug for RegistrationError

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

Formats the value using the given formatter.

impl Display for RegistrationError

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

Formats the value using the given formatter.

impl Error for RegistrationError

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.
