Trait SockAddr

pub unsafe trait SockAddr {

    unsafe fn sockaddr_raw_mut(&mut self) -> (*mut sockaddr, socklen_t);
}
Expand description

A trait implemented by all socket address types.

Safety:

  • Implementers must ensure that the two raw methods always return valid pointers and lengths for the kernel to refer to. The pointers should always be to a sockaddr-shaped structure, which always starts with an sa_family_t field describing the protocol family that the address belongs to.
  • Both methods must return a pointer to the same memory so that writes through the mut pointer will be visible to reads through the const pointer.

Required Methods§

Source

unsafe fn sockaddr_raw_const(&self) -> (*const sockaddr, socklen_t)

Returns a raw const pointer and the length of what it points to for use when sending a socket address to the kernel.

Safety: Caller must ensure that self remains valid throughout all use of the returned pointer and that use of it is consistent with a shared borrow.

Source

unsafe fn sockaddr_raw_mut(&mut self) -> (*mut sockaddr, socklen_t)

Returns a raw mut pointer and the length of what it points to for use when retrieving a socket address from the kernel.

Safety: Caller must ensure that self remains valid throughout all use of the returned pointer and that use of it is consistent with a mutable borrow.
