## BlockingIoSource

# Struct BlockingIoSource

Source

    struct BlockingIoSource {
        fd: WeakFileDescriptionRef<dyn SourceFileDescription>,
        blocked_threads: BTreeMap<ThreadId, BlockingIoInterest>,
    }

## Fields§

§`fd: WeakFileDescriptionRef<dyn SourceFileDescription>`

The source file description which is registered into the poll. We only store weak references such that source file descriptions can be destroyed whilst they are registered. However, they are required to deregister themselves when `FileDescription::destroy` is called.

§`blocked_threads: BTreeMap<ThreadId, BlockingIoInterest>`

The threads which are blocked on the I/O source, and the interest indicating when they should be unblocked.

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
