Enum abin::Boo

pub enum Boo<'a, TBorrowed, TOwned> where
    TBorrowed: ?Sized,  {
    Borrowed(&'a TBorrowed),
    Owned(TOwned),
}

A borrowed-or-owned type (boo).

Similar to std::borrow::Cow but without the requirement of TBorrowed : ToOwned<Owned=TOwned>.

Variants

Borrowed(&'a TBorrowed)

It's borrowed.

Owned(TOwned)

It's owned.

Implementations

impl<'a, TBorrowed, TOwned> Boo<'a, TBorrowed, TOwned> where
    TOwned: Borrow<TBorrowed>,
    TBorrowed: ?Sized, 

pub fn into_owned_with<TBooToOwned>(self) -> TOwned where
    TBooToOwned: BooToOwned<TBorrowed, TOwned>,
