Implementations

impl<T> ReferenceOr<T>

pub fn ref_(r: &str) -> ReferenceOr<T>

pub fn boxed_item(item: T) -> ReferenceOr<Box<T>>

pub fn into_item(self) -> Option<T>

Converts this ReferenceOr to the item inside, if it exists.

The return value will be Option::Some if this was a ReferenceOr::Item or Option::None if this was a ReferenceOr::Reference.

Examples

let i = ReferenceOr::Item(1);
assert_eq!(i.into_item(), Some(1));

let j: ReferenceOr<u8> = ReferenceOr::Reference { reference: String::new() };
assert_eq!(j.into_item(), None);

pub fn as_item(&self) -> Option<&T>

Returns a reference to to the item inside this ReferenceOr, if it exists.

The return value will be Option::Some if this was a ReferenceOr::Item or Option::None if this was a ReferenceOr::Reference.

Examples

let i = ReferenceOr::Item(1);
assert_eq!(i.as_item(), Some(&1));

let j: ReferenceOr<u8> = ReferenceOr::Reference { reference: String::new() };
assert_eq!(j.as_item(), None);

impl<T> ReferenceOr<Box<T>>

pub fn unbox(self) -> ReferenceOr<T>

Trait Implementations

impl<T> Clone for ReferenceOr<T>

where T: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ReferenceOr<T>

where T: Debug,

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

Formats the value using the given formatter.

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

where T: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<ReferenceOr<T>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> PartialEq for ReferenceOr<T>

where T: PartialEq,

fn eq(&self, other: &ReferenceOr<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> Serialize for ReferenceOr<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
