Struct arc_swap::access::Constant [−][src]
pub struct Constant<T>(pub T);
Expand description
Access to an constant.
This wraps a constant value to provide Access
to it. It is constant in the sense that,
unlike ArcSwapAny
and Map
, the loaded value will always stay the same (there’s no
remote store
).
The purpose is mostly testing and plugging a parameter that works generically from code that doesn’t need the updating functionality.
