Enum Error 

pub enum Error<S, Q> {
    Connection(S),
    Query(Q),
    ConnectionNotFound(ConnectionHandle),
    QueryNotFound(QueryHandle),
    InvalidOpcode(Opcode),
    InvalidResponseCode(ResponseCode),
    TrancatedQuery,
    Proto(ProtoError),
}

The error type for the server.

Variants

Connection(S)

The server is full and cannot hold any more connections.

Query(Q)

The connection is full and cannot hold any more queries.

ConnectionNotFound(ConnectionHandle)

The connection is not found.

QueryNotFound(QueryHandle)

The query is not found.

InvalidOpcode(Opcode)

Returned when the a query has an invalid opcode.

InvalidResponseCode(ResponseCode)

Returned when the a query has an invalid response code.

TrancatedQuery

Proto(ProtoError)

Protocol error

Trait Implementations

impl<S: Debug, Q: Debug> Debug for Error<S, Q>

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

Formats the value using the given formatter.

impl<S, Q> Display for Error<S, Q>

where S: Display, Q: Display,

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

Formats the value using the given formatter.

impl<S, Q> Error for Error<S, Q>

where S: Error, Q: Error, Self: Debug + Display,

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.

impl<S, Q> From<Error> for Error<S, Q>

fn from(source: ProtoError) -> Self

Converts to this type from the input type.
