Enum HasOneModel 

pub enum HasOneModel<E: EntityTrait> {
    NotSet,
    Set(Box<E::ActiveModelEx>),
}

Container for belongs_to or has_one relation

Variants

NotSet

Unspecified value, do nothing

Set(Box<E::ActiveModelEx>)

Specify the value for the has one relation

Implementations

impl<E> HasOneModel<E>

where E: EntityTrait,

pub fn set<AM: Into<E::ActiveModelEx>>(model: AM) -> Self

Construct a HasOneModel::Set

pub fn replace<AM: Into<E::ActiveModelEx>>(&mut self, model: AM)

pub fn take(&mut self) -> Option<E::ActiveModelEx>

Take ownership of this model, leaving NotSet in place

pub fn as_ref(&self) -> Option<&E::ActiveModelEx>

Get a reference, if set

pub fn as_mut(&mut self) -> Option<&mut E::ActiveModelEx>

Get a mutable reference, if set

pub fn is_set(&self) -> bool

Return true if there is a model

pub fn is_not_set(&self) -> bool

Return true if self is NotSet

pub fn is_none(&self) -> bool

Return true if self is NotSet

pub fn is_changed(&self) -> bool

Return true if the containing model is set and changed

pub fn into_option(self) -> Option<E::ActiveModelEx>

Convert into an Option<ActiveModelEx>

pub fn try_into_model(self) -> Result<HasOne<E>, DbErr>

where E::ActiveModelEx: TryIntoModel<E::ModelEx>,

Trait Implementations

impl<E: Clone + EntityTrait> Clone for HasOneModel<E>

where E::ActiveModelEx: Clone,

fn clone(&self) -> HasOneModel<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug + EntityTrait> Debug for HasOneModel<E>

where E::ActiveModelEx: Debug,

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

Formats the value using the given formatter.

impl<E: EntityTrait> Default for HasOneModel<E>

fn default() -> HasOneModel<E>

Returns the “default value” for a type.

impl<E> PartialEq<Option<<E as EntityTrait>::ActiveModelEx>> for HasOneModel<E>

where E: EntityTrait, E::ActiveModelEx: PartialEq,

fn eq(&self, other: &Option<E::ActiveModelEx>) -> 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.

impl<E> PartialEq for HasOneModel<E>

where E: EntityTrait, E::ActiveModelEx: PartialEq,

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

impl<E> Eq for HasOneModel<E>
