Struct tor_persist::state_dir::StorageHandle
source · pub struct StorageHandle<T> { /* private fields */ }
Available on crate feature
state-dir
only.Expand description
A place in the state or cache directory, where we can load/store a serialisable type
Implies exclusive access.
Rust mutability-xor-sharing rules enforce proper synchronisation,
unless multiple StorageHandle
s are created
using the same InstanceStateHandle
and key.
