Enum RegistryErrorKind 

pub enum RegistryErrorKind {
    AuthenticationFailure,
    MalformedRequest,
    RejectedRequest,
    TemporarilyUnavailable,
    ServerError,
    NotDelivered,
    NoAnswer,
    ProtocolViolation,
}

How a whole request to the study registry failed. Failures of single items are answers, not these.

Variants

AuthenticationFailure

Our credentials.

MalformedRequest

Our request, including one refused before it left.

RejectedRequest

Another refusal of the request as a whole.

TemporarilyUnavailable

The registry’s own lookups failed before anything was written or sent.

ServerError

NotDelivered

The connection itself failed, so the request provably never arrived.

NoAnswer

The request left and no answer arrived, as on a timeout.

ProtocolViolation

An answer arrived that was not a batch answer.

Implementations

impl RegistryErrorKind

pub fn may_have_been_acted_on(self) -> bool

Whether the registry may have acted on the request. An import that may have landed must be verified rather than re-sent, or a transcript gets a second attainment.

pub fn is_outage(self) -> bool

Whether the registry or the network is down rather than anything being wrong with the request, so the same request may succeed once they are back.

Trait Implementations

impl Clone for RegistryErrorKind

fn clone(&self) -> RegistryErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegistryErrorKind

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

Formats the value using the given formatter.

impl PartialEq for RegistryErrorKind

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