Enum scylla::transport::errors::RequestError

#[non_exhaustive]
pub enum RequestError {
    CqlRequestSerialization(CqlRequestSerializationError),
    BodyExtensionsParseError(FrameBodyExtensionsParseError),
    CqlResponseParseError(CqlResponseParseError),
    BrokenConnection(BrokenConnectionError),
    UnableToAllocStreamId,
}

An error that occurred when performing a request.

Possible error kinds:

• Connection is broken
• Response’s frame header deserialization error
• CQL response (frame body) deserialization error
• Driver was unable to allocate a stream id for a request

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CqlRequestSerialization(CqlRequestSerializationError)

Failed to serialize CQL request.

BodyExtensionsParseError(FrameBodyExtensionsParseError)

Failed to deserialize frame body extensions.

CqlResponseParseError(CqlResponseParseError)

Failed to deserialize a CQL response (frame body).

BrokenConnection(BrokenConnectionError)

A connection was broken during request execution.

UnableToAllocStreamId

Driver was unable to allocate a stream id to execute a request on.

Trait Implementations

impl Debug for RequestError

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

Formats the value using the given formatter.

impl Display for RequestError

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

Formats the value using the given formatter.

impl Error for RequestError

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

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.
