Trait Implementations§

impl Clone for Lazy

source§

fn clone(&self) -> Lazy

source§

impl Debug for Lazy

source§

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

Formats the value using the given formatter. Read more
source§

impl PartialEq<Lazy> for Lazy

source§

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
source§

impl StructuralPartialEq for Lazy

source§

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.
