Struct BorrowedSocket

1.63.0 · Source
pub struct BorrowedSocket<'socket> { /* private fields */ }
Expand description

A borrowed socket.

This has a lifetime parameter to tie it to the lifetime of something that owns the socket.

This uses repr(transparent) and has the representation of a host socket, so it can be used in FFI in places where a socket is passed as an argument, it is not captured or consumed, and it never has the value INVALID_SOCKET.

This type’s .to_owned() implementation returns another BorrowedSocket rather than an OwnedSocket. It just makes a trivial copy of the raw socket, which is then borrowed under the same lifetime.

Implementations§

Source§

impl BorrowedSocket<'_>

1.63.0 (const: 1.63.0) · Source

pub const unsafe fn borrow_raw(socket: u32) -> BorrowedSocket<'_>

Returns a BorrowedSocket holding the given raw socket.

§Safety

The resource pointed to by raw must remain open for the duration of the returned BorrowedSocket, and it must not have the value INVALID_SOCKET.

Source§

impl BorrowedSocket<'_>

1.63.0 · Source

pub fn try_clone_to_owned(&self) -> Result<OwnedSocket, Error>

Creates a new OwnedSocket instance that shares the same underlying object as the existing BorrowedSocket instance.
