pub type BorrowedFilelike<'filelike> = BorrowedFd<'filelike>;
Expand description

A reference to a filelike object.

This is a portability abstraction over Unix-like BorrowedFd and Windows’ BorrowedHandle.

Aliased Type§

struct BorrowedFilelike<'filelike> { /* private fields */ }

Implementations§

impl BorrowedFd<'_>

1.63.0 (const: 1.63.0) · source

pub const unsafe fn borrow_raw(fd: i32) -> BorrowedFd<'_>

Return a BorrowedFd holding the given raw file descriptor.

Safety

The resource pointed to by fd must remain open for the duration of the returned BorrowedFd, and it must not have the value -1.
