Tuple Fields

0: Vec<u8>

Implementations

impl Query

pub fn new() -> QueryBuilder<QueryStatement>

Create CQL query by following the cql binary v4 specs

pub fn with_capacity(capacity: usize) -> QueryBuilder<QueryStatement>

Create CQL query with_capacity by following the cql binary v4 specs

impl Query

pub fn from_payload_unchecked(payload: Vec<u8>) -> Query

Create a Query from a payload without validating it. This assumes that the user knows for certain that the payload is a valid Query payload. Otherwise, using it as one will likely cause panics.

pub fn convert_to_execute(&mut self) -> Result<&mut Self>

Convert a Query frame into an Execute frame. Will return an error if the frame is not a Query frame.

pub fn convert_to_query(&mut self, stmt: &str) -> Result<&mut Query>

Convert an Execute frame into a Query frame. Will return an error if the frame is not an Execute frame.

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

Performs copy-assignment from source.

impl Default for Query

fn default() -> Query

Returns the “default value” for a type.

impl Into<Vec<u8>> for Query

fn into(self) -> Vec<u8>
