Error type for all errors from this crate

The E generic argument is used for user-defined error types, eg. when the user provides a callback.

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.

NotInBrowser

Not running in a browser window

IndexedDbDisabled

IndexedDB is disabled

OperationNotSupported

Operation is not supported by the browser

OperationNotAllowed

Operation is not allowed by the user agent

InvalidKey

Provided key is not valid

VersionMustNotBeZero

Version must not be zero

VersionTooOld

Requested version is older than existing version

InvalidCall

The requested function cannot be called from this context

InvalidArgument

The provided arguments are invalid

AlreadyExists

Cannot create something that already exists

DoesNotExist

Cannot change something that does not exists

DatabaseIsClosed

Database is closed

ObjectStoreWasRemoved

Object store was removed

ReadOnly

Transaction is read-only

FailedClone

Unable to clone

InvalidRange

Invalid range

CursorCompleted

Cursor finished its range

User(E)

User-provided error to pass through indexed-db code

Trait Implementations

impl<E: Clone> Clone for Error<E>

fn clone(&self) -> Error<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for Error<E>

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

Formats the value using the given formatter.

impl<E> Display for Error<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Error for Error<E>

where E: Error, Self: Debug + Display,

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<E> From<E> for Error<E>

fn from(source: E) -> Self

Converts to this type from the input type.
