Struct NullableValue 

pub struct NullableValue<'i>(/* private fields */);

Wrapper type that can be used to display nullable column value represented as Option<Value>.

Trait Implementations

impl<'i> Clone for NullableValue<'i>

fn clone(&self) -> NullableValue<'i>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'i> Debug for NullableValue<'i>

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

Formats the value using the given formatter.

impl<'i> Display for NullableValue<'i>

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

Formats the value using the given formatter.

impl<'i> PartialEq for NullableValue<'i>

fn eq(&self, other: &NullableValue<'i>) -> 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.
