pub struct Fragile<T> { /* private fields */ }
Expand description

A Fragile<T> wraps a non sendable T to be safely send to other threads.

Once the value has been wrapped it can be sent to other threads but access to the value on those threads will fail.

If the value needs destruction and the fragile wrapper is on another thread the destructor will panic. Alternatively you can use Sticky<T> which is not going to panic but might temporarily leak the value.

Implementations

Creates a new Fragile wrapping a value.

The value that is moved into the Fragile can be non Send and will be anchored to the thread that created the object. If the fragile wrapper type ends up being send from thread to thread only the original thread can interact with the value.

Returns true if the access is valid.

This will be false if the value was sent to another thread.

Consumes the Fragile, returning the wrapped value.

Panics

Panics if called from a different thread than the one where the original value was created.

Consumes the Fragile, returning the wrapped value if successful.

The wrapped value is returned if this is called from the same thread as the one where the original value was created, otherwise the Fragile is returned as Err(self).

Immutably borrows the wrapped value.

Panics

Panics if the calling thread is not the one that wrapped the value. For a non-panicking variant, use try_get.

Mutably borrows the wrapped value.

Panics

Panics if the calling thread is not the one that wrapped the value. For a non-panicking variant, use try_get_mut.

Tries to immutably borrow the wrapped value.

Returns None if the calling thread is not the one that wrapped the value.

Tries to mutably borrow the wrapped value.

Returns None if the calling thread is not the one that wrapped the value.
