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", so this trait is not object safe.
