Function sp_std::ptr::dangling_mut

pub const fn dangling_mut<T>() -> *mut T

🔬This is a nightly-only experimental API. (strict_provenance)

Creates a new pointer that is dangling, but well-aligned.

This is useful for initializing types which lazily allocate, like Vec::new does.

Note that the pointer value may potentially represent a valid pointer to a T, which means this must not be used as a “not yet initialized” sentinel value. Types that lazily allocate must track initialization by some other means.
