Struct arc_swap::gen_lock::PrivateSharded[−][src]

pub struct PrivateSharded<S> { /* fields omitted */ }
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.
