Struct StorageLevel 

pub struct StorageLevel {
    pub use_disk: bool,
    pub use_memory: bool,
    pub use_off_heap: bool,
    pub deserialized: bool,
    pub replication: i32,
}

Re-exported so persist(...) / storage_level() have a public storage-level type. StorageLevel for persisting Datasets/Tables.

Fields

use_disk: bool

(Required) Whether the cache should use disk or not.

use_memory: bool

(Required) Whether the cache should use memory or not.

use_off_heap: bool

(Required) Whether the cache should use off-heap or not.

deserialized: bool

(Required) Whether the cached data is deserialized or not.

replication: i32

(Required) The number of replicas.
