Superset of all other errors that can occur. Convenience enum so that users can convert all errors into a single type

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.

DatabaseAlreadyOpen

The Database is already open. Cannot acquire lock.

InvalidSavepoint

This savepoint is invalid because an older savepoint was restored after it was created

PersistentSavepointExists

A persistent savepoint exists

Corrupted(String)

The Database is corrupted

UpgradeRequired(u8)

The database file is in an old file format and must be manually upgraded

ValueTooLarge(usize)

The value being inserted exceeds the maximum of 3GiB

TableTypeMismatch

Fields

table: String

key: TypeName

value: TypeName

Table types didn’t match.

TableIsMultimap(String)

The table is a multimap table

TableIsNotMultimap(String)

The table is not a multimap table

TypeDefinitionChanged

Fields

name: TypeName

alignment: usize

width: Option<usize>

TableDoesNotExist(String)

Table name does not match any table in database

TableAlreadyOpen(String, &'static Location<'static>)

Io(Error)

LockPoisoned(&'static Location<'static>)

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 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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
