WebbTo support such data structures, Rust provides a number of APIs that offer so-called interior mutability: the ability to mutate data via method calls on a shared reference. Unfortunately, the existing APIs sacrifice flexibility, concurrent access, and/or performance, in exchange for safety. WebbUn invariant important maintenu par le runtime Kotlin/Native est que l'objet appartient soit à un seul thread/worker, soit qu'il est immuable ( shared XOR mutable ). Cela garantit que les mêmes données ont un seul mutateur, et qu'il n'y a …

WebbReturns a shared reference to the value. If the value may be uninitialized, as_uninit_ref must be used instead. For the mutable counterpart see as_mut. Safety When calling this method, you have to ensure that all of the following is true: The pointer must be properly aligned. WebbAnd the thing is that shared and mutable references have different variances. Shared references are covariant, and mutable references are invariant.
