Struct tikv::storage::LatchLock[][src]

pub struct LatchLock {
    pub required_hashes: Vec<u64>,
    pub owned_count: usize,
}

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]

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.

pub fn is_write_lock(&self) -> bool[src]
