Trait Implementations

impl Clone for ColumnDef

fn clone(&self) -> ColumnDef

Returns a copy 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.
