Struct DeletePlan 

pub struct DeletePlan {
    pub delete: Vec<RowRef>,
    pub set_null: Vec<SetNullUpdate>,
    pub restricted: Vec<RestrictedConstraint>,
}

Result of planning a delete against a schema.

Fields

delete: Vec<RowRef>

Rows to delete, in an order that respects dependencies (children first).

set_null: Vec<SetNullUpdate>

Child rows whose foreign-key columns must be nulled before the parent is deleted.

restricted: Vec<RestrictedConstraint>

Constraints that would be violated if the delete proceeded.

Trait Implementations

impl Clone for DeletePlan

fn clone(&self) -> DeletePlan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeletePlan

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

Formats the value using the given formatter.

impl Default for DeletePlan

fn default() -> DeletePlan

Returns the “default value” for a type.

impl Eq for DeletePlan

impl PartialEq for DeletePlan

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