Struct QueryParams

pub struct QueryParams {
    pub consistency: Consistency,
    pub with_names: bool,
    pub values: Option<QueryValues>,
    pub page_size: Option<CInt>,
    pub paging_state: Option<CBytes>,
    pub serial_consistency: Option<Consistency>,

}

Parameters of Query for query operation.

Fields

consistency: Consistency

Cassandra consistency level.

with_names: bool

Were values provided with names

values: Option<QueryValues>

Array of values.

page_size: Option<CInt>

Page size.

paging_state: Option<CBytes>

Array of bytes which represents paging state.

serial_consistency: Option<Consistency>

Serial Consistency.

timestamp: Option<CLong>

Timestamp.

keyspace: Option<String>

Keyspace indicating the keyspace that the query should be executed in. It supersedes the keyspace that the connection is bound to, if any.

now_in_seconds: Option<CInt>

Represents the current time (now) for the query. Affects TTL cell liveness in read queries and local deletion time for tombstones and TTL cells in update requests.

Trait Implementations

impl Clone for QueryParams

fn clone(&self) -> QueryParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryParams

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

Formats the value using the given formatter.

impl Default for QueryParams

fn default() -> QueryParams

Returns the “default value” for a type.

impl FromCursor for QueryParams

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

Tries to parse Self from a cursor of bytes.

impl PartialEq for QueryParams

fn eq(&self, other: &QueryParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for QueryParams

fn serialize(&self, cursor: &mut Cursor<&mut Vec<u8>>, version: Version)

Serializes given value using the cursor.

fn serialize_to_vec(&self, version: Version) -> Vec<u8>

Wrapper for easily starting hierarchical serialization.

impl Eq for QueryParams
