Transactional variable

Implementations

source

impl<T> TVar<T> where
T: Clone + Any + Send + Sync,

source

pub fn new(data: T) -> Self

Instantiates transactional variable for later use in a transaction.

source

pub fn new_with_timeout(data: T, timeout: usize) -> Self

New transactional variable with overridden timeout for overriding timeout for specific transactional variable.

Highly discouraged for the daily use unless you have various code paths that can interfere over the variable that you instantiate.

source

pub fn get_data(&self) -> T

Get’s the underlying data for the transactional variable.

Beware that this will not give correct results any given point in time during the course of execution of a transaction.
