Trait Implementations

impl Clone for OptionDbValue

fn clone(&self) -> OptionDbValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionDbValue

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

Formats the value using the given formatter.

impl Default for OptionDbValue

fn default() -> OptionDbValue

Returns the “default value” for a type.

impl From<Option<DbValue>> for OptionDbValue

fn from(o: Option<DbValue>) -> OptionDbValue

Converts to this type from the input type.

impl From<OptionDbValue> for Option<DbValue>

fn from(o: OptionDbValue) -> Option<DbValue>

Converts to this type from the input type.

impl PartialEq for OptionDbValue

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