Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a copy 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

Define a column for an Entity

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. It only cast text as enum type if it’s an enum column.

Get the name of the entity the column belongs to

get the name of the entity the column belongs to
