Trait Implementations

impl<'a> Clone for StatementNamed<'a>

fn clone(&self) -> StatementNamed<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'c, 's, C> Execute<'c, C> for StatementNamed<'s>

where C: Prepare + 'c, 's: 'c,

type ExecuteOutput = ResultFuture<IntoGuarded<'c, Pin<Box<dyn Future<Output = Result<Statement, Error>> + Send + 'c>>, C>>

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

type QueryOutput = <StatementNamed<'s> as Execute<'c, C>>::ExecuteOutput

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

fn execute(self, cli: &'c C) -> Self::ExecuteOutput

define how a statement is executed with single time response

fn query(self, cli: &'c C) -> Self::QueryOutput

define how a statement is queried with repeated response
