Enum OptionDiff 

pub enum OptionDiff<T: Diffable> {
    Removed(T),
    Added(T),
    Changed(<T as Diffable>::Repr),
    Unchanged,
}

Enum representing the difference between two Option values.

Variants

Removed(T)

Indicates that a value was removed (i.e., Some became None).

Added(T)

Indicates that a value was added (i.e., None became Some).

Changed(<T as Diffable>::Repr)

Indicates that the inner value of Some has changed.

Unchanged

Indicates that the value has not changed.

Trait Implementations

impl<T: Diffable> Changeable for OptionDiff<T>

fn is_changed(&self) -> bool

Checks if the object has changed.

fn is_unchanged(obj: &Self) -> bool

Static method to check if an object has not changed.

impl<T: Debug + Diffable> Debug for OptionDiff<T>

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

Formats the value using the given formatter.

impl<T: Diffable> Default for OptionDiff<T>

fn default() -> OptionDiff<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for OptionDiff<T>

where T: Deserialize<'de> + Diffable,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> PartialEq for OptionDiff<T>

where T: Diffable + PartialEq, <T as Diffable>::Repr: PartialEq,

fn eq(&self, other: &Self) -> 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> Serialize for OptionDiff<T>

where T: Serialize + Diffable,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
