Set the indexed field to true

pub fn default_value<T>(self, value: T) -> Self

where T: Into<Value>,

Set the default value

pub fn default<T>(self, default: T) -> Self

where T: Into<SimpleExpr>,

Set the default value or expression of a column

pub fn get_column_type(&self) -> &ColumnType

Get ColumnType as reference

pub fn get_column_default(&self) -> Option<&SimpleExpr>

Trait Implementations

impl Clone for ColumnDef

fn clone(&self) -> ColumnDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ColumnTypeTrait for ColumnDef

fn def(self) -> ColumnDef

Instantiate a new ColumnDef

fn get_enum_name(&self) -> Option<&DynIden>

Get the name of the enum if this is a enum column

impl Debug for ColumnDef

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

Formats the value using the given formatter.

impl PartialEq for ColumnDef

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