Data race error

A data race is similar to a race condition and happens when:

• Two or more pointers access the same data at the same time.
• At least one of the pointers is being used to write to the data.
• There's no synchronization mechanism to protect the data.

Data races cause undefined behavior and are hard to debug.

Rust prevents data races by allowing only a single mutable reference of a value per scope.
