Extension trait for QueryBuilder to add eager loading support

Required Methods

fn with(self, relation: &str) -> QueryBuilderWithEagerLoading<M>

Add a relationship to eagerly load

fn with_where<F>( self, relation: &str, constraint: F, ) -> QueryBuilderWithEagerLoading<M>

where F: FnOnce(RelationshipConstraintBuilder) -> RelationshipConstraintBuilder + 'static,

Add a relationship with constraints

fn with_when( self, condition: bool, relation: &str, ) -> QueryBuilderWithEagerLoading<M>

Add conditional eager loading

fn with_count(self, relation: &str) -> QueryBuilderWithEagerLoading<M>

Load relationship counts without loading the relationships

fn with_count_where<F>( self, alias: &str, relation: &str, constraint: F, ) -> QueryBuilderWithEagerLoading<M>

where F: FnOnce(RelationshipConstraintBuilder) -> RelationshipConstraintBuilder + 'static,

Load relationship counts with constraints

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
