Implementations

impl DefaultValue

pub fn to_sql(&self) -> String

Returns the SQL representation of the default value.

Trait Implementations

impl Clone for DefaultValue

fn clone(&self) -> DefaultValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DefaultValue

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

Formats the value using the given formatter.

impl PartialEq for DefaultValue

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