BorrowedCStream

Struct BorrowedCStream 

Source
pub struct BorrowedCStream<'a> { /* private fields */ }
Expand description

A borrowed RawCStream.

This has a lifetime parameter to tie it to the lifetime of something that owns the stream. For the duration of that lifetime, it is guaranteed that nobody will close the stream.

This uses #[repr(transparent)] and has the representation of a host stream, so it can be used in FFI in places where a file descriptor is passed as an argument, it is not captured or consumed, and it never has the value NULL.

This type’s Clone implementation returns another BorrowedCStream rather than an OwnedCStream. It just makes a trivial copy of the raw file descriptor, which is then borrowed under the same lifetime.

Implementations§

Source§

impl<'a> BorrowedCStream<'a>

Source

pub const unsafe fn borrow_raw(raw: RawCStream) -> Self

Return a BorrowedCStream holding the given stream.

§Safety

The resource pointed to by raw must remain open for the duration of the returned BorrowedCStream.
