Struct io_lifetimes::OwnedFd

source · [−]

#[repr(transparent)]
pub struct OwnedFd { /* private fields */ }

Expand description

An owned file descriptor.

This closes the file descriptor on drop.

This uses repr(transparent) and has the representation of a host file descriptor, so it can be used in FFI in places where a file descriptor is passed as a consumed argument or returned as an owned value, and it never has the value -1.

Implementations
