Struct tikv::storage::LatchLock [−][src]
Lock required for a command.
Fields
required_hashes: Vec<u64>
The hash value of the keys that a command must acquire before being able to be processed.
owned_count: usize
The number of latches that the command has acquired.
Implementations
impl Lock
[src][−]
pub fn new<'a, K, I>(keys: I) -> Lock where
K: Hash + 'a,
I: IntoIterator<Item = &'a K>,
[src][−]
K: Hash + 'a,
I: IntoIterator<Item = &'a K>,
Creates a lock specifing all the required latches for a command.
pub fn acquired(&self) -> bool
[src][−]
Returns true if all the required latches have be acquired, false otherwise.
