Enum cassandra_protocol::frame::frame_result::ResResultBody

pub enum ResResultBody {
    Void,
    Rows(BodyResResultRows),
    SetKeyspace(BodyResResultSetKeyspace),
    Prepared(BodyResResultPrepared),
    SchemaChange(SchemaChange),
}

ResponseBody is a generalized enum that represents all types of responses. Each of enum option wraps related body type.

Variants

Void

Void response body. It’s an empty struct.

Rows(BodyResResultRows)

Tuple Fields

0: BodyResResultRows

Rows response body. It represents a body of response which contains rows.

SetKeyspace(BodyResResultSetKeyspace)

Tuple Fields

0: BodyResResultSetKeyspace

Set keyspace body. It represents a body of set_keyspace query and usually contains a name of just set namespace.

Prepared(BodyResResultPrepared)

Tuple Fields

0: BodyResResultPrepared

Prepared response body.

SchemaChange(SchemaChange)

Tuple Fields

0: SchemaChange

Schema change body

Implementations

impl ResResultBody

pub fn into_rows(self) -> Option<Vec<Row>>

It converts body into Vec<Row> if body’s type is Row and returns None otherwise.

pub fn as_rows_metadata(&self) -> Option<RowsMetadata>

It returns Some rows metadata if frame result is of type rows and None otherwise

pub fn into_prepared(self) -> Option<BodyResResultPrepared>

Unwraps body and returns BodyResResultPrepared which contains an exact result of PREPARE query.

pub fn into_set_keyspace(self) -> Option<BodyResResultSetKeyspace>

Unwraps body and returns BodyResResultSetKeyspace which contains an exact result of use keyspace query.

impl ResResultBody

pub fn from_cursor(
    cursor: &mut Cursor<&[u8]>,
    version: Version
) -> Result<ResResultBody>
