Struct StatementPreparedQuery 

pub struct StatementPreparedQuery<'a, P> { /* private fields */ }

a named and already prepared statement with it’s query params

after Execute::query by certain excutor it would produce RowStream as response

Implementations

impl<'a, P> StatementPreparedQuery<'a, P>

pub fn into_owned(self) -> StatementPreparedQueryOwned<'a, P>

Trait Implementations

impl<'s, P> Encode for StatementPreparedQuery<'s, P>

where P: AsParams,

type Output = &'s [Column]

output type defines how a potential async row streaming type should be constructed. certain state from the encode type may need to be passed for constructing the stream

fn encode(self, buf: &mut BytesMut) -> Result<Self::Output, Error>

impl<'s, P> Execute<&Client> for StatementPreparedQuery<'s, P>

where P: AsParams,

type ExecuteOutput = ResultFuture<RowAffected>

outcome of execute. used for single time database response: number of rows affected by execution for example.

type QueryOutput = Ready<Result<GenericRowStream<&'s [Column], Typed>, Error>>

outcome of query. used for repeated database response: database rows for example

fn execute(self, cli: &Client) -> Self::ExecuteOutput

define how a statement is executed with single time response

fn query(self, cli: &Client) -> Self::QueryOutput

define how a statement is queried with repeated response

impl<'s, C, P> ExecuteBlocking<&C> for StatementPreparedQuery<'s, P>

where C: ClientBorrow, P: AsParams,

type ExecuteOutput = Result<u64, Error>

type QueryOutput = Result<GenericRowStream<&'s [Column], Typed>, Error>

fn execute_blocking(self, cli: &C) -> Result<u64, Error>

fn query_blocking(self, cli: &C) -> Self::QueryOutput
