}

The different set of errors that arroy can encounter.

Variants

Heed(Error)

An internal error mostly related to LMDB or encoding/decoding.

Io(Error)

IO error

InvalidVecDimension

The user is trying to insert or search for a vector that is not of the right dimensions.

Fields

expected: usize

The expected number of dimensions.

received: usize

The dimensions given by the user.

DatabaseFull

An internal error returned when arroy cannot generate internal IDs.

InvalidItemAppend

The user tried to append an item in the database but the last inserted item is highler or equal to this one.

UnmatchingDistance

The user is trying to query a database with a distance that is not of the right type.

Fields

expected: String

The expected distance type.

received: &'static str

The distance given by the user.

MissingMetadata(u16)

Arroy is not able to find the metadata for a given index. It is probably because the user forget to build the database.

NeedBuild(u16)

The last time items in the database were updated, the [Writer::build] method wasn’t called.

MissingKey

Internal error

Fields

index: u16

The index that caused the error

mode: &'static str

The kind of item that was being queried

item: ItemId

The item ID queried

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
