Enum scylla::transport::errors::MetadataError

#[non_exhaustive]
pub enum MetadataError {
    Peers(PeersMetadataError),
    Keyspaces(KeyspacesMetadataError),
    Udts(UdtMetadataError),
    Tables(TablesMetadataError),
    Views(ViewsMetadataError),
}

An error that occurred during cluster metadata fetch.

An error can occur during metadata fetch of:

• peers
• keyspaces
• UDTs
• tables
• views

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.

Peers(PeersMetadataError)

Bad peers metadata.

Keyspaces(KeyspacesMetadataError)

Bad keyspaces metadata.

Udts(UdtMetadataError)

Bad UDTs metadata.

Tables(TablesMetadataError)

Bad tables metadata.

Views(ViewsMetadataError)

Bad views metadata.

Trait Implementations

impl Clone for MetadataError

fn clone(&self) -> MetadataError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MetadataError

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

Formats the value using the given formatter.

impl Display for MetadataError

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

Formats the value using the given formatter.

impl Error for MetadataError

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>)
