Struct raft::storage::MemStorage

pub struct MemStorage { /* fields omitted */ }

MemStorage is a thread-safe implementation of Storage trait. It is mainly used for test purpose.

Methods

impl MemStorage

pub fn new() -> MemStorage

Returns a new memory storage value.

pub fn rl(&self) -> RwLockReadGuard<MemStorageCore>

Opens up a read lock on the storage and returns a guard handle. Use this with functions that don't require mutation.

pub fn wl(&self) -> RwLockWriteGuard<MemStorageCore>

Opens up a write lock on the storage and returns guard handle. Use this with functions that take a mutable reference to self.
