Enum RegistryError 

#[non_exhaustive]
pub enum RegistryError {
    AlreadyExists(String),
    NotFound(String),
    UnsupportedAlgorithm(IndexAlgorithm),
    Engine(StoreError),
}

Errors returned by the registry.

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.

AlreadyExists(String)

An index with that name already exists.

NotFound(String)

No index registered under that name.

UnsupportedAlgorithm(IndexAlgorithm)

The schema asks for an algorithm the engine does not implement yet (today: IndexAlgorithm::Flat).

Engine(StoreError)

Engine-level failure during Engine::in_memory.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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 From<StoreError> for RegistryError

fn from(source: StoreError) -> Self

Converts to this type from the input type.
