Enum RegistryErrorKind 

pub enum RegistryErrorKind {
    NotFound,
    Unauthorized,
    NetworkError,
    ServerError,
    Other,
}

The kind of failure that occurred during a Registry operation.

Registry implementations classify their errors into these kinds so that the engine (and ultimately the user) can distinguish between a missing spec, an authorization failure, a network outage, etc.

Variants

NotFound

The requested spec or type was not found (e.g. HTTP 404).

Unauthorized

The request was unauthorized or forbidden (e.g. HTTP 401, 403).

NetworkError

A network or transport error occurred (DNS failure, timeout, connection refused).

ServerError

The registry server returned an internal error (e.g. HTTP 5xx).

Other

An error that does not fit the other categories.

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 Display 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.
