Struct arc_swap::access::Map [−][src]
pub struct Map<A, T, F> { /* fields omitted */ }
Expand description
An adaptor to provide access to a part of larger structure.
This is the active part of this module. Use the module documentation for the details.
Implementations
Creates a new instance.
Parameters
access
: Access to the bigger structure. This is usually something likeArc<ArcSwap>
or&ArcSwap
. It is technically possible to use any otherAccess
here, though, for example to sub-delegate into even smaller structure from aMap
(or genericAccess
).projection
: A function (or closure) responsible to providing a reference into the bigger bigger structure, selecting just subset of it. In general, it is expected to be cheap (like only taking reference).
