Struct rbatis_core::query_as::QueryAs

#[must_use = "query must be executed to affect database"]pub struct QueryAs<'q, DB, O> where
    DB: Database,  { /* fields omitted */ }

Raw SQL query with bind parameters, mapped to a concrete type using FromRow. Returned by query_as.

Implementations

impl<'q, DB, O> QueryAs<'q, DB, O> where
    DB: Database, 

pub fn bind<T>(self, value: T) -> Self where
    T: Type<DB>,
    T: Encode<DB>, 

Bind a value for use with this SQL query.
