Enum LazyLoadStrategy 

pub enum LazyLoadStrategy {
    Select,
    Joined,
    Subquery,
    Selectin,
    Dynamic,
    NoLoad,
    RaiseOnSql,
    WriteOnly,
}

Lazy loading strategy for relationships.

Controls how and when related objects are loaded from the database. Maps to SQLAlchemy’s relationship lazy parameter.

Variants

Select

Load items on first access via separate SELECT (default).

Joined

Eager load via JOIN in parent query.

Subquery

Eager load via separate SELECT using IN clause.

Selectin

Eager load via subquery correlated to parent.

Dynamic

Return a query object instead of loading items (for large collections).

NoLoad

Never load - access raises error (useful for write-only relationships).

RaiseOnSql

Always raise error on access (strict write-only).

WriteOnly

Write-only collection (append/remove only, no iteration).

Trait Implementations

impl Clone for LazyLoadStrategy

fn clone(&self) -> LazyLoadStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LazyLoadStrategy

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

Formats the value using the given formatter.

impl Default for LazyLoadStrategy

fn default() -> LazyLoadStrategy

Returns the “default value” for a type.

impl PartialEq for LazyLoadStrategy

fn eq(&self, other: &LazyLoadStrategy) -> 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.
