Struct QueryData 

pub struct QueryData<E>
where
    E: EntityTrait,
    E::ModelEx: BaseEntity,
    <E::ModelEx as BaseEntity>::LoaderType: EntityLoaderTrait<E, ModelEx = E::ModelEx>,
{
    pub loader: <E::ModelEx as BaseEntity>::LoaderType,
    pub opts: RepositoryOptions<NoUser>,
    pub order_asc: Option<bool>,
}

Builder wrapping a SeaORM entity loader with pagination and hydration settings.

E is the SeaORM entity being queried; its model must implement BaseEntity so cursor pagination can use id comparisons. order_asc records the cursor direction (Some(true) ascending, Some(false) descending).

Fields

loader: <E::ModelEx as BaseEntity>::LoaderType

The entity loader used to load relations for this entity type.

opts: RepositoryOptions<NoUser>

Limit/cursor/distinct/detach settings applied at execution time.

order_asc: Option<bool>

Recorded ordering direction for cursor filtering, if any ordering was set.

Implementations

impl<E> QueryData<E>

where E: EntityTrait, E::ModelEx: BaseEntity, <E::ModelEx as BaseEntity>::LoaderType: EntityLoaderTrait<E, ModelEx = E::ModelEx>,

pub fn new(loader: <E::ModelEx as BaseEntity>::LoaderType) -> Self

Wraps an entity loader with default options and no ordering.

pub fn with_options<U>(self, opts: RepositoryOptions<U>) -> Self

where U: BaseEntity + Clone + Send + Sync + 'static,

Copies limit, cursor, distinct, detach, correlation, and transaction settings from the given options.

pub fn order_by(self, asc: bool) -> Self

Orders by id and records the direction for cursor filtering.

pub fn order_by_asc(self) -> Self

Orders by ascending id and records ascending cursor direction.

pub fn order_by_desc(self) -> Self

Orders by descending id and records descending cursor direction.

pub fn distinct(self) -> Self

Marks the select distinct and records the distinct flag in options.

pub fn filter<F>(self, f: F) -> Self

where F: FnOnce(<E::ModelEx as BaseEntity>::LoaderType) -> <E::ModelEx as BaseEntity>::LoaderType,

Applies a filter to the loader via the given closure.

pub fn with_limit(self, limit: u64) -> Self

Sets the select limit and records it in options.
