Trait Implementations

impl Clone for Model

fn clone(&self) -> Model

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Model

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

Formats the value using the given formatter.

impl Default for Model

fn default() -> Model

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Model

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Model> for ActiveModel

fn from(m: Model) -> Self

Converts to this type from the input type.

impl From<Model> for HummockPinnedSnapshot

fn from(value: Model) -> Self

Converts to this type from the input type.

impl FromQueryResult for Model

fn from_query_result(row: &QueryResult, pre: &str) -> Result<Self, DbErr>

Instantiate a Model from a [QueryResult]

fn from_query_result_optional( res: &QueryResult, pre: &str, ) -> Result<Option<Self>, DbErr>

Transform the error from instantiating a Model from a [QueryResult] and converting it to an Option

fn find_by_statement(stmt: Statement) -> SelectorRaw<SelectModel<Self>>

impl IntoActiveModel<ActiveModel> for Model

fn into_active_model(self) -> ActiveModel

Method to call to perform the conversion

impl ModelTrait for Model

type Entity = Entity

fn get(&self, c: <Self::Entity as EntityTrait>::Column) -> Value

Get the [Value] of a column from an Entity

fn set(&mut self, c: <Self::Entity as EntityTrait>::Column, v: Value)

Set the [Value] of a column in an Entity

fn find_related<R>(&self, _: R) -> Select<R>

where R: EntityTrait, Self::Entity: Related<R>,

Find related Models

fn find_linked<L>(&self, l: L) -> Select<<L as Linked>::ToEntity>

where L: Linked<FromEntity = Self::Entity>,

Find linked Models

fn delete<'a, 'async_trait, A, C>( self, db: &'a C, ) -> Pin<Box<dyn Future<Output = Result<DeleteResult, DbErr>> + Send + 'async_trait>>

where 'a: 'async_trait, Self: IntoActiveModel<A> + 'async_trait, C: ConnectionTrait + 'async_trait, A: ActiveModelTrait<Entity = Self::Entity> + ActiveModelBehavior + Send + 'a + 'async_trait,

Delete a model

impl PartialEq for Model

fn eq(&self, other: &Model) -> 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 Serialize for Model

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<ActiveModel> for Model

type Error = DbErr

The type returned in the event of a conversion error.

fn try_from(a: ActiveModel) -> Result<Self, DbErr>

Performs the conversion.

impl TryIntoModel<Model> for ActiveModel

fn try_into_model(self) -> Result<Model, DbErr>

Method to call to perform the conversion

impl Eq for Model

impl StructuralPartialEq for Model
