Trait abi_stable::std_types::cow::RCowCompatibleRef

pub trait RCowCompatibleRef<'a>: ToOwned {
    type RefC: IntoOwned<ROwned = Self::ROwned, Target = Self>;
    type ROwned: Borrow<Self> + Into<Self::Owned> + From<Self::Owned>;

    // Required methods
    fn as_c_ref(from: &'a Self) -> Self::RefC;
    fn as_rust_ref(from: Self::RefC) -> &'a Self;
}

For making a Cow<'a, Self> convertible into an RCow.

Required Associated Types

type RefC: IntoOwned<ROwned = Self::ROwned, Target = Self>

The (preferably) ffi-safe equivalent of &Self.

type ROwned: Borrow<Self> + Into<Self::Owned> + From<Self::Owned>

The owned version of Self::RefC.

Required Methods

fn as_c_ref(from: &'a Self) -> Self::RefC

Converts a reference to an FFI-safe type

fn as_rust_ref(from: Self::RefC) -> &'a Self

Converts an FFI-safe type to a reference

Object Safety

This trait is not object safe.
