Enum ClientError

pub enum ClientError {
    Io(Error),
    Utf8Parse(FromUtf8Error),
    Auth,
    CommandFailed {
        message: String,
    },
    QueryFailed(QueryFailed),
}

The error type for the DB operations of the Client, Query and associated structs and traits.

Errors mostly occur while communicating with the database, but can also happen e.g. when parsing arguments.

Variants

Io(Error)

The database connection stream or parsing arguments has resulted in an error.

Utf8Parse(FromUtf8Error)

The byte sequence being parsed is not a valid UTF-8 sequence.

Auth

The provided credentials for authorizing are invalid.

CommandFailed

The command was processed but failed to get the expected result.

Fields

message: String

QueryFailed(QueryFailed)

The query was processed but failed to get the expected result.

Trait Implementations

impl Debug for ClientError

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

Formats the value using the given formatter.

impl Display for ClientError

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

Formats the value using the given formatter.

impl Error for ClientError

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 From<Error> for ClientError

fn from(err: Error) -> ClientError

Converts to this type from the input type.

impl From<FromUtf8Error> for ClientError

fn from(err: FromUtf8Error) -> ClientError

Converts to this type from the input type.
