Enum PassiveDeletes 

pub enum PassiveDeletes {
    Active,
    Passive,
    All,
}

Passive delete behavior for relationships.

Controls whether the ORM emits DELETE statements for related objects or relies on the database’s foreign key ON DELETE cascade behavior.

Variants

Active

ORM emits DELETE for related objects (default behavior).

Passive

ORM relies on database ON DELETE CASCADE; no DELETE emitted. The database foreign key must have ON DELETE CASCADE configured.

All

Like Passive, but also disables orphan tracking entirely. Use when you want complete database-side cascade with no ORM overhead.

Trait Implementations

impl Clone for PassiveDeletes

fn clone(&self) -> PassiveDeletes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PassiveDeletes

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

Formats the value using the given formatter.

impl Default for PassiveDeletes

fn default() -> PassiveDeletes

Returns the “default value” for a type.

impl PartialEq for PassiveDeletes

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