Struct arc_swap::gen_lock::PrivateSharded
source · [−]pub struct PrivateSharded<S> { /* private fields */ }Expand description
An alternative to PrivateUnsharded, but with configurable number of shards.
The PrivateUnsharded is almost identical to PrivateSharded<[Shard; 1]> (the
implementation takes advantage of some details to avoid a little bit of overhead). It allows
the user to choose the trade-of between contention during locking and size of the pointer and
speed during writes.
Note on AsRef<[Shard]>
Rust provides the AsRef trait (or, actually any trait) up to arrays of 32 elements. If you
need something bigger, you have to work around it with a newtype.
