Struct cdrs::cluster::session::Session

pub struct Session<LB> {
    pub compression: Compression,
    /* private fields */
}

CDRS session that holds one pool of authorized connecitons per node. compression field contains data compressor that will be used for decompressing data received from Cassandra server.

Fields

compression: Compression

Implementations

impl<'a, LB: Sized> Session<LB>

pub fn paged<T: CDRSTransport + 'static, M: ManageConnection<Connection = RefCell<T>, Error = Error>>(
    &'a self,
    page_size: i32
) -> SessionPager<'a, M, Session<LB>, T>where
    Session<LB>: CDRSSession<'static, T, M>,

Basing on current session returns new SessionPager that can be used for performing paged queries.

impl<'a, L> Session<L>

pub fn listen<A: Authenticator + 'static + Sized>(
    &self,
    node: &str,
    authenticator: A,
    events: Vec<SimpleServerEvent>
) -> Result<(Listener<RefCell<TransportTcp>>, EventStream)>

Returns new event listener.

impl<'a, LB> GetCompressor<'a> for Session<LB>

fn get_compressor(&self) -> Compression

Returns compression that current session has.

impl<T: CDRSTransport + Send + Sync + 'static, M: ManageConnection<Connection = RefCell<T>, Error = Error> + Sized, LB: LoadBalancingStrategy<Pool<M>>> GetConnection<T, M> for Session<LB>

impl<'a, T: CDRSTransport + 'static, LB: LoadBalancingStrategy<Pool<M>> + Sized, M: ManageConnection<Connection = RefCell<T>, Error = Error> + Sized> PrepareExecutor<T, M> for Session<LB>

fn prepare_tw<Q: ToString>(
    &self,
    query: Q,
    with_tracing: bool,
    with_warnings: bool
) -> Result<PreparedQuery>

It prepares a query for execution, along with query itself the method takes with_tracing and with_warnings flags to get tracing information and warnings.

fn prepare<Q: ToString>(&self, query: Q) -> Result<PreparedQuery>

It prepares query without additional tracing information and warnings.

fn query<Q: ToString>(&self, query: Q) -> Result<Frame>

Executes a query with default parameters:

fn query_tw<Q: ToString>(
    &self,
    query: Q,
    with_tracing: bool,
    with_warnings: bool
) -> Result<Frame>

Executes a query with ability to trace it and see warnings, and default parameters:

fn query_with_values<Q: ToString, V: Into<QueryValues>>(
    &self,
    query: Q,
    values: V
) -> Result<Frame>

    &self,
    query: Q,
    values: V,
    with_tracing: bool,
    with_warnings: bool
) -> Result<Frame>

Executes a query with bounded values (either with or without names) and ability to see warnings, trace a request and default parameters.

fn query_with_params<Q: ToString>(
    &self,
    query: Q,
    query_params: QueryParams
) -> Result<Frame>
