Enum RelationLoadStrategy 

pub enum RelationLoadStrategy {
    Separate,
    Join,
    Lazy,
}

Strategy for loading relations.

Variants

Separate

Load relations in separate queries (default, N+1 safe with batching).

Join

Load relations using JOINs (single query, good for one-to-one/many-to-one).

Lazy

Load relations lazily on access.

Implementations

impl RelationLoadStrategy

pub fn is_separate(&self) -> bool

Check if this is a separate query strategy.

pub fn is_join(&self) -> bool

Check if this is a join strategy.

pub fn is_lazy(&self) -> bool

Check if this is lazy loading.

Trait Implementations

impl Clone for RelationLoadStrategy

fn clone(&self) -> RelationLoadStrategy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RelationLoadStrategy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RelationLoadStrategy

fn default() -> RelationLoadStrategy

Returns the “default value” for a type.

impl PartialEq for RelationLoadStrategy

fn eq(&self, other: &RelationLoadStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
