The first is when interfacing with C code, and the second is when building
certain kinds of abstractions.
Rust has support for FFI, (which you can read about in the [FFI
Guide](guide-ffi.html)) but Rust can't guarantee that the C code will be safe,
like Rust's will. Therefore, Rust marks such functions with the `unsafe`

Therefore, Rust marks such functions with the `unsafe`
keyword, which indicates that the function may not behave properly.
Second, if you'd like to create some sort of shared-memory data structure, Rust
