Variants

AddTask(Error)

can’t add task

SerializeStep(Error, String)

DeserializeStep(Error, String)

can’t deserialize step (the task was likely changed between the scheduling and running of the step): {1}

UnlockStaleTasks(Error)

can’t unlock stale tasks

ListenerConnect(Error)

waiter can’t connect to the db

ListenerListen(Error)

can’t start listening for tables changes

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)>

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.
