Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ColumnTrait for Column

type EntityName = Entity

fn def(&self) -> ColumnDef

Get the column definition with SQL attributes

fn enum_type_name(&self) -> Option<&'static str>

Get the enum type name if this is a enum column

fn select_as(&self, expr: Expr) -> SimpleExpr

Cast column expression used in select statement. It only cast database enum as text if it’s an enum column.

fn save_as(&self, val: Expr) -> SimpleExpr

Cast value of a column into the correct type for database storage. By default, it only cast text as enum type if it’s an enum column.

fn json_key(&self) -> &'static str

Available on crate feature with-json only.

Get the JSON key for deserialization.

fn entity_name(&self) -> DynIden

Get the name of the entity the column belongs to

fn as_column_ref(&self) -> (DynIden, DynIden)

Get the table.column reference

fn eq<V>(&self, v: V) -> Expr

where V: Into<Value>,

Perform equality against a Value. None will be converted to IS NULL.

fn ne<V>(&self, v: V) -> Expr

where V: Into<Value>,

Perform inequality against a Value. None will be converted to IS NOT NULL.

fn gt<V>(&self, v: V) -> Expr

where V: Into<Value>,

fn gte<V>(&self, v: V) -> Expr

where V: Into<Value>,

fn lt<V>(&self, v: V) -> Expr

where V: Into<Value>,

fn lte<V>(&self, v: V) -> Expr

where V: Into<Value>,

fn between<V>(&self, a: V, b: V) -> Expr

where V: Into<Value>,

fn not_ilike<T>(&self, s: T) -> Expr

where T: IntoLikeExpr,

Postgres Only.

fn starts_with<T>(&self, s: T) -> Expr

where T: Into<String>,

This is a simplified shorthand for a more general like method. Use like if you need something more complex, like specifying an escape character.

fn ends_with<T>(&self, s: T) -> Expr

where T: Into<String>,

This is a simplified shorthand for a more general like method. Use like if you need something more complex, like specifying an escape character.

fn contains<T>(&self, s: T) -> Expr

where T: Into<String>,

This is a simplified shorthand for a more general like method. Use like if you need something more complex, like specifying an escape character.

fn if_null<V>(&self, v: V) -> Expr

where V: Into<Value>,
