Struct StorageFlags 

#[repr(transparent)]
pub struct StorageFlags(pub i32);

StorageDeltaFlags under the name storage handles use for it: the flags (today only ExclusiveLock) a transaction requests for a key it writes. Flags that can be set on a storage delta to modify its behavior. Multiple flags can be combined using bitwise OR.

Tuple Fields

0: i32

Implementations

impl StorageDeltaFlags

pub const None: StorageDeltaFlags

pub const ExclusiveLock: StorageDeltaFlags
