Implementations§

source§

impl<T> ReferenceOr<T>

source

pub fn ref_(r: &str) -> Self

source

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

source

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);
source

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);
