Struct relational_types::OneToMany[−][src]

pub struct OneToMany<T, U> { /* fields omitted */ }

A one to many relation, i.e. to one T corresponds many U, and a U has one corresponding T.

Implementations

impl<T, U> OneToMany<T, U> where
    T: Id<T>,
    U: Id<U> + Id<T>, [src]

pub fn new(
    one: &CollectionWithId<T>,
    many: &CollectionWithId<U>,
    rel_name: &str
) -> Result<Self, Error>[src]

Construct the relation automatically from the 2 given CollectionWithIds.
