Transaction lifecycle failure (lock conflict, shutdown, etc.)

Catalog(CatalogError)

Catalog operation failure

Binder(BinderError)

Binder (semantic analysis) failure

Planner(PlannerError)

Logical planner failure

Processor(ProcessorError)

Query processor / execution failure

Parser(String)

Parser failure

Io(Error)

Internal(String)

Internal invariant violation (should never happen)

Trait Implementations

impl Debug for AkarError

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

Formats the value using the given formatter.

impl Display for AkarError

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

Formats the value using the given formatter.

impl Error for AkarError

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.
