DuplicateId(DeviceId)

A device with this ID already exists.

NotFound(DeviceId)

No device has this ID.

InvalidConfig(ConfigError)

The plugin rejected the config.

UnsupportedFault

fault: FaultId

The fault that was asked for.

Implementations

impl RegistryError

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

A stable, machine-readable code for API error bodies ({ error: { code, … } }).

use hardless_core::RegistryError;
assert_eq!(RegistryError::UnknownKind("x".into()).code(), "unknown_kind");

Trait Implementations

impl Clone for RegistryError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegistryError

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

Formats the value using the given formatter.

impl Display for RegistryError

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

Formats the value using the given formatter.

impl Eq for RegistryError

impl Error for RegistryError

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.

impl PartialEq for RegistryError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
