Trait Implementations

impl Clone for Lazy

fn clone(&self) -> Lazy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Lazy

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq<Lazy> for Lazy

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl StructuralPartialEq for Lazy

impl Sync for Lazy

This is requires because UnsafeRef(*mut Variable) can not be sent across threads. The lack of UnsafeRef variant when sending across threads is guaranteed at language level. The interior of UnsafeRef can not be accessed outside this library.
