Struct query_structure::filter::OneRelationIsNullFilter

pub struct OneRelationIsNullFilter {
    pub field: RelationField,
}

Filter that is solely responsible for checking if a to-one related record is null. Todo there’s no good, obvious reason why this is a separate filter.

Fields

field: RelationField

impl Clone for OneRelationIsNullFilter

fn clone(&self) -> OneRelationIsNullFilter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OneRelationIsNullFilter

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

Formats the value using the given formatter.

impl From<OneRelationIsNullFilter> for Filter

fn from(sf: OneRelationIsNullFilter) -> Self

Converts to this type from the input type.

impl Hash for OneRelationIsNullFilter

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OneRelationIsNullFilter

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

This method tests for self and other values to be equal, and is used by ==.

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

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