Enum openraft::StorageError

pub enum StorageError<NID>
where
    NID: NodeId,
{
    Defensive {
        source: DefensiveError<NID>,
    },
    IO {
        source: StorageIOError<NID>,
    },
}

A storage error could be either a defensive check error or an error occurred when doing the actual io operation.

It indicates a data crash. An application returning this error will shutdown the Openraft node immediately to prevent further damage.

Variants

Defensive

An error raised by defensive check.

Fields

source: DefensiveError<NID>

IO

An error raised by io operation.

Fields

source: StorageIOError<NID>

impl<NID> Error for StorageError<NID>

where NID: NodeId, DefensiveError<NID>: Error, StorageIOError<NID>: Error, Self: Debug + Display,

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

The lower-level source of this error, if any.

fn provide<'_request>(&'_request self, request: &mut Request<'_request>)

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

Provides type based access to context intended for error reports.

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

impl<NID> From<DefensiveError<NID>> for StorageError<NID>

where NID: NodeId,

fn from(source: DefensiveError<NID>) -> Self

Converts to this type from the input type.

impl<C: RaftTypeConfig, E: Error> From<StorageError<<C as RaftTypeConfig>::NodeId>> for StreamingError<C, E>

fn from(source: StorageError<C::NodeId>) -> Self

Converts to this type from the input type.

impl<NID> From<StorageError<NID>> for Fatal<NID>

where NID: NodeId,

fn from(source: StorageError<NID>) -> Self

Converts to this type from the input type.

impl<NID, E> From<StorageError<NID>> for RaftError<NID, E>

where NID: NodeId,
