Rust pointer type
WebbIn a secure Rust development, any function pointer types at the FFI boundary must be marked extern (possibly with the specific ABI) and unsafe. Function pointers in Rust are … Webb3 juni 2024 · Since the layout of fat pointers is a Rust-specific concept, they should never be accessed via FFI. This means that only thin pointers should be used, all of which have …

WebbThe XArray is an abstract data type which behaves like a very large array of pointers. Add a Rust abstraction for this data type. The initial implementation uses explicit locking on get operations and returns a guard which blocks mutation, ensuring that the referenced object remains alive.

WebbIt has a static type system. In C, all executable code is contained within subroutines (also called "functions", though not in the sense of functional programming ). Function parameters are passed by value, although arrays are passed as pointers, i.e. the address of the first item in the array. WebbActually, I just realized that this is not ok for unsized types. When T is unsized, the raw pointer is a fat pointer with a vtable, and the vtable part is not necessarily zeroable. However, it would be ok to do it for `*const [T]` since the fat part of the pointer is just the length in this case, and a length of zero is fine. See more here:

Type similarity and such. Even more tempting: CString has … WebbThe Rust Programming Language Smart Pointers A pointer is a general concept for a variable that contains an address in memory. This address refers to, or “points at,” some other data. The most common kind of pointer in Rust is a reference, which you learned about in Chapter 4.

For example, u8 is Unpin, so Pin<&mut u8> behaves just like a normal &mut u8. However, types that can't be moved after they're pinned have a marker called !Unpin.
