Struct sunrise_fs::interface::storage::PartitionStorage

pub struct PartitionStorage {
    inner: Arc<Mutex<Box<dyn IStorage<Error = Error>>>>,
    partition_start: u64,
    partition_len: u64,
}

Wrapper over a IStorage that permit to access only a partition.

Fields

inner: Arc<Mutex<Box<dyn IStorage<Error = Error>>>>

The backing IStorage implementation

partition_start: u64

The start of the partition.

partition_len: u64

The size of the partition.

Implementations

impl PartitionStorage

pub fn new(
    inner: Arc<Mutex<Box<dyn IStorage<Error = Error>>>>,
    partition_start: u64,
    partition_len: u64
) -> Self

Create a new PartitionStorage
