Struct ScopePtr 

pub struct ScopePtr<K, V>(/* private fields */);

Smart pointer retaining ownership of a scope so it can be reactivated after it has been popped from the table. Port of PersistentScopedMapScopePtr; Rc’s automatic reference counting replaces the manual addRef/decRef pair.

Implementations

impl<K, V> ScopePtr<K, V>

pub fn is_null(&self) -> bool

Return true if this pointer is null.

pub fn reset(&mut self)

Free the scope reference and set the pointer to null.

Trait Implementations

impl<K, V> Clone for ScopePtr<K, V>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K, V> Default for ScopePtr<K, V>

fn default() -> Self

Returns the “default value” for a type.

impl<K, V> PartialEq for ScopePtr<K, V>

fn eq(&self, other: &Self) -> bool

Pointer identity, like the C++ operator== (ptr_ == other.ptr_).

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
