Struct DbSet 

pub struct DbSet<T: IEntityType> { /* private fields */ }

Implementations

impl<T: IEntityType + IEntitySnapshot> DbSet<T>

pub fn new(table_name: impl Into<String>) -> Self

pub fn with_provider( table_name: impl Into<String>, provider: Arc<dyn IDatabaseProvider>, ) -> Self

pub fn set_query_filter(&mut self, filter: BoolExpr)

pub fn set_filter_map(&mut self, map: Arc<HashMap<String, CompiledFilter>>)

Sets the global filter map (table_name → BoolExpr) used by NavigationLoader to scope secondary queries.

pub fn set_provider(&mut self, provider: Arc<dyn IDatabaseProvider>)

pub fn tracked_entries(&self) -> impl Iterator<Item = &T>

Returns an iterator over entity references.

pub fn tracked_entries_mut(&mut self) -> impl Iterator<Item = &mut T>

Returns a mutable iterator over entity references.

pub fn retain(&mut self, f: impl FnMut(&DbSetEntry<T>) -> bool)

Retains entries matching the predicate (drops others).

pub fn clear_entries(&mut self)

Convenience inherent method — delegates to IDbSet::clear_entries.

pub fn len(&self) -> usize

Convenience inherent method — delegates to IDbSet::len.

pub fn is_empty(&self) -> bool

Convenience inherent method — delegates to IDbSet::is_empty.

pub fn query(&self) -> QueryBuilder<T>

Convenience inherent method — delegates to IQueryable::query.

pub fn query_ignore_filters(&self) -> QueryBuilder<T>

Returns a query builder that bypasses the configured query filter. Use for administrative / cross-tenant queries.

pub fn filter<F>(&self, apply: F) -> QueryBuilder<T>

where F: FnOnce(QueryBuilder<T>) -> QueryBuilder<T>,

Starts a query filtered by a compile-time LINQ expression tree (linq!())

pub async fn exists_by_id( &self, key_values: HashMap<String, DbValue>, ) -> EFResult<bool>

where T: IFromRow + INavigationSetter + IGetKeyValues + IEntitySnapshot + ILazyInit,

Checks whether an entity with the given key values exists in the database.

fn clear_entries(&mut self)

Clears all entries from the set (does not affect ChangeTracker).

fn len(&self) -> usize

Returns the number of entries.

fn is_empty(&self) -> bool

Returns whether the set is empty.
