Struct Attacher 

pub struct Attacher<S> { /* private fields */ }

Available on crate feature runtime only.

Attach a handle to the driver of current thread.

A handle can and only can attach once to one driver. The attacher will try to attach the handle.

Implementations

impl<S> Attacher<S>

pub unsafe fn new_unchecked(source: S) -> Attacher<S>

Create Attacher without trying to attach the source.

Safety

• The user should ensure that the source is attached to the current driver.
• S should be an owned fd.

pub unsafe fn from_shared_fd_unchecked(source: SharedFd<S>) -> Attacher<S>

Create Attacher without trying to attach the source.

Safety

See Attacher::new_unchecked.

impl<S> Attacher<S>

where S: AsFd,

pub fn new(source: S) -> Result<Attacher<S>, Error>

Create Attacher. It tries to attach the source, and will return Err if it fails.

Platform specific

• IOCP: a handle could not be attached more than once. If you want to clone the handle, create the Attacher before cloning.
