pub struct Arc<T>(/* private fields */);Expand description
A reference-counted pointer that can only be constructed through a
crate::ValueCache.
Arc<T> wraps std::sync::Arc<T> and implements Deref<Target = T>,
Clone, Debug, Display, PartialEq, Eq, and Hash identically.
Use Arc::into_std or Arc::as_std to interoperate with APIs that
require std::sync::Arc<T> explicitly.
Implementations§

impl<T> Arc<T>
Sourcepub fn as_std(&self) -> &StdArc<T>
pub fn as_std(&self) -> &StdArc<T>
Returns a reference to the underlying std::sync::Arc<T>.
Sourcepub fn into_std(self) -> StdArc<T>
pub fn into_std(self) -> StdArc<T>
Converts into the underlying std::sync::Arc<T>.
Sourcepub fn unwrap_or_clone(this: Self) -> Twhere
T: Clone,
pub fn unwrap_or_clone(this: Self) -> Twhere
T: Clone,
Unwraps the inner value if this is the only strong reference; otherwise clones it.
