Trait pg_worm::query::Executable

pub trait Executable {
    type Output;

    // Required method
    fn exec<'async_trait>(
        self
    ) -> Pin<Box<dyn Future<Output = Result<Self::Output, Error>> + Send + 'async_trait>>
       where Self: 'async_trait;
}

Trait used to mark exectuable queries. It is used to make use of generics for executing them.

Required Associated Types

type Output

What output should this query result in?

Required Methods

fn exec<'async_trait>( self ) -> Pin<Box<dyn Future<Output = Result<Self::Output, Error>> + Send + 'async_trait>>where Self: 'async_trait,

The actual function for executing a query.

Implementors

impl<'a> Executable for Query<'a, u64>

type Output = u64

impl<'a, T> Executable for Query<'a, Option<T>>where T: TryFrom<Row, Error = Error> + Send,

type Output = Option<T>

impl<'a, T> Executable for Query<'a, Vec<T>>where T: TryFrom<Row, Error = Error> + Send,

type Output = Vec<T, Global>
