Struct Q 

pub struct Q<'scope> { /* private fields */ }

An opaque value you can use to compose together queries.

To get a value of this type, use query.

Implementations

impl<'scope> Q<'scope>

pub fn q<T: Table<'scope>>(&mut self, query: Query<T>) -> T

Bind a query and give you a value representing each row it produces.

The 'scope lifetime prevents this value leaking out of its context, which would result in invalid queries.

pub fn where_<'a>(&mut self, expr: Expr<'a, bool>)

where 'scope: 'a,

Introduce a where clause for this query.

If you introduce a clause that looks like a.id = b.a_id then you effectively create an inner join.
