Struct mio::sys::unix::waker::eventfd::WakerInternal

pub struct WakerInternal {
    fd: File,
}

Waker backed by eventfd.

eventfd is effectively an 64 bit counter. All writes must be of 8 bytes (64 bits) and are converted (native endian) into an 64 bit unsigned integer and added to the count. Reads must also be 8 bytes and reset the count to 0, returning the count.

Fields

fd: File
