Rust Raw Pointers
Syntax
- let raw_ptr = &pointee as *const type // create constant raw pointer to some data
- let raw_mut_ptr = &mut pointee as *mut type // create mutable raw pointer to some mutable data
- let deref = *raw_ptr // dereference a raw pointer (requires unsafe block)
Remarks
- Raw pointers are not guaranteed to point to a valid memory address and as such, careless usage may lead to unexpected (and probably fatal) errors.
- Any normal Rust reference (eg.
&my_objectwhere the type ofmy_objectis T) will coerce to*const T. Similarly, mutable references coerce to*mut T. - Raw pointers do not move ownership (in contrast to Box values that)
