Enum Error

#[non_exhaustive]
pub enum Error {
    UuidTaken,
    Datastore(Box<dyn StdError + Send + Sync>),
    Io(Error),
    NotIndexed,
    Unsupported,
    Invalid(ValidationError),
    OperationOnQuery,
}

An error triggered by the datastore.

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.

UuidTaken

The requested UUID is already taken.

Datastore(Box<dyn StdError + Send + Sync>)

An error occurred in the underlying datastore.

Io(Error)

A generic I/O error occurred.

NotIndexed

A query occurred on a property that isn’t indexed.

Unsupported

For functionality that isn’t supported.

Invalid(ValidationError)

A validation error occurred.

OperationOnQuery

The operation cannot work with the given query, based off it’s output type (e.g. attempting to delete using a query that outputs a count.)

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

Formats the value using the given formatter.

impl Error for Error

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