Struct std::os::wasi::io::OwnedFd
#[repr(transparent)]pub struct OwnedFd { /* fields omitted */ }
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.
