Trait ReadOnlyClone 

pub trait ReadOnlyClone {
    type ReadOnly;

    // Required method
    fn read_only_clone(&self) -> Self::ReadOnly;
}

Trait for creating read-only clones of composite types.

For stored vecs, delegates to StoredVec::read_only_clone. For containers (Option, BTreeMap, cohort groups), propagates to inner types. For Traversable-derived types with M: StorageMode, the derive macro generates an impl that maps Self<Rw> → Self<Ro>.

Required Associated Types

type ReadOnly

Required Methods

fn read_only_clone(&self) -> Self::ReadOnly

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<K: Clone + Ord, V: ReadOnlyClone> ReadOnlyClone for BTreeMap<K, V>

type ReadOnly = BTreeMap<K, <V as ReadOnlyClone>::ReadOnly>

fn read_only_clone(&self) -> BTreeMap<K, V::ReadOnly>

impl<T: ReadOnlyClone, const N: usize> ReadOnlyClone for [T; N]

type ReadOnly = [<T as ReadOnlyClone>::ReadOnly; N]

fn read_only_clone(&self) -> [T::ReadOnly; N]

impl<T: ReadOnlyClone> ReadOnlyClone for Option<T>

type ReadOnly = Option<<T as ReadOnlyClone>::ReadOnly>
