Trait Implementations

impl<T: Clone + FromValue> Clone for OptionIr2<T>

where T::Intermediate: Clone,

fn clone(&self) -> OptionIr2<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + FromValue> Debug for OptionIr2<T>

where T::Intermediate: Debug,

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

Formats the value using the given formatter.

impl<T: FromValue> From<OptionIr2<T>> for Option<T>

fn from(ir: OptionIr2<T>) -> Self

Converts to this type from the input type.

impl<T: FromValue> From<OptionIr2<T>> for Value

where <T as FromValue>::Intermediate: Into<Value>,

fn from(ir: OptionIr2<T>) -> Self

Converts to this type from the input type.

impl<T: PartialEq + FromValue> PartialEq for OptionIr2<T>

where T::Intermediate: PartialEq,

fn eq(&self, other: &OptionIr2<T>) -> 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.

impl<T: FromValue> TryFrom<Value> for OptionIr2<T>

type Error = <<T as FromValue>::Intermediate as TryFrom<Value>>::Error

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>

Performs the conversion.
