pub struct DataLock<T> { /* fields omitted */ }

An exclusive access lock around the given data

Methods

impl<T> DataLock<T>

pub fn new(value: T) -> Self

Create a new data access guarding lock

pub fn try_lock(&self) -> Option<TryDataLock<T>>

Try to lock the guarded data for mutual exclusive access. Returns None if the lock failes or Some(TryDataLock). The actual data, the TryDataLock wraps could be conviniently accessed by dereferencing it.

Example

    let secure_data: DataLock<u32> = DataLock::new(10);
 
    if let Some(data) = secure_data.try_lock() {
        assert_eq!(*data, 10);
    }
