Struct Scope 

pub struct Scope<'m, K: Eq + Hash + Copy, V: Clone> { /* private fields */ }

RAII for creating and popping a scope. Port of PersistentScopedMapScope.

Implementations

impl<'m, K: Eq + Hash + Copy, V: Clone> Scope<'m, K, V>

pub fn new(base: &'m PersistentScopedMap<K, V>) -> Self

Create (and activate) a new child scope of base’s current scope.

pub fn depth(&self) -> u32

\return the depth of the scope.

pub fn ptr(&self) -> ScopePtr<K, V>

Return a persistent pointer that retains ownership of the scope so it can be reactivated after it has been popped.

Trait Implementations

impl<'m, K: Eq + Hash + Copy, V: Clone> Drop for Scope<'m, K, V>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
