Struct Prefetch 

pub struct Prefetch<M: Model, T: Model> { /* private fields */ }

prefetch_related request: a relation and, optionally, the queryset used to load the targets (to filter them, order them or use another handle).

Implementations

impl<M: Model, T: Model> Prefetch<M, T>

pub fn new(relation: Relation<M, T>) -> Self

Prefetch relation with a plain queryset over the target.

pub fn queryset(self, queryset: QuerySet<T>) -> Self

Load targets through queryset. Its filters apply; targets it does not return stay unloaded. Its database capabilities and compiled existing bind count govern prefetch batching. SQL backends must implement Backend::read_parameter_count.

Trait Implementations

impl<M: Model, T: Model> From<Relation<M, T>> for Prefetch<M, T>

fn from(relation: Relation<M, T>) -> Self

Converts to this type from the input type.
