Trait BorrowOrShare

pub trait BorrowOrShare<'i, 'o, T: ?Sized>: Bos<T> {
    // Required method
    fn borrow_or_share(&'i self) -> &'o T;
}

A helper trait for writing “data borrowing or sharing” functions.

See the crate-level documentation for more details.

Required Methods

fn borrow_or_share(&'i self) -> &'o T

Borrows from *self or from behind a reference it holds.

In the latter case, the returned reference is said to be shared with *self.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<'i, 'o, T: ?Sized, B> BorrowOrShare<'i, 'o, T> for B

where B: Bos<T> + ?Sized + 'i, B::Ref<'i>: 'o,
