Struct FdWrapper

source 
pub struct FdWrapper<T: AsRawFd>(/* private fields */);
Expand description

Wrapper to use a type implementing AsRawFd but not AsFd with Generic

Implementations§

source§

impl<T: AsRawFd> FdWrapper<T>

source

pub unsafe fn new(inner: T) -> Self

Wrap inner with an AsFd implementation.

§Safety

This is safe if the AsRawFd implementation of inner always returns a valid fd. This should usually be true for types implementing AsRawFd. But this isn’t guaranteed with FdWrapper<RawFd>.
