I don't know what examples you've been seeing. The interop structs are just regular Rust structs with the `#[repr(C)]` attribute applied to them, to ensure that the Rust compiler lays the struct out exactly as the C compiler for that target ABI would. Rust code can access their fields just fine. There's no strict need for accessor functions.

And vice versa. Rust code and C code can both operate on each other’s structs natively.

`#[repr(C)]` instructs the compiler to lay the struct out exactly according to C’s rules: order, alignment, padding, size, etc. Without this, the compiler is allowed a lot more freedom when laying out a struct.
