Enum cassandra_protocol::error::Error

pub enum Error {
    Io(Error),
    UuidParse(UuidError),
    General(String),
    FromUtf8(FromUtf8Error),
    Utf8(Utf8Error),
    Compression(CompressionError),
    Server(ErrorBody),
    Timeout(String),
}

CDRS custom error type. CDRS expects two types of error - errors returned by Server and internal errors occurred within the driver itself. Occasionally io::Error is a type that represent internal error because due to implementation IO errors only can be raised by CDRS driver. Server error is an error which are ones returned by a Server via result error frames.

Variants

Io(Error)

Internal IO error.

UuidParse(UuidError)

Internal error that may be raised during uuid::Uuid::from_bytes

General(String)

General error

FromUtf8(FromUtf8Error)

Internal error that may be raised during String::from_utf8

Utf8(Utf8Error)

Internal error that may be raised during str::from_utf8

Compression(CompressionError)

Internal Compression/Decompression error

Server(ErrorBody)

Server error.

Timeout(String)

Timed out waiting for an operation to complete.

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)>

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

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
