pub struct Interest(_);
Expand description

Readiness event interest.

Specifies the readiness events the caller is interested in when awaiting on I/O resource readiness states.

Implementations

Interest in all readable events.

Readable interest includes read-closed events.

Interest in all writable events.

Writable interest includes write-closed events.

Returns true if the value includes readable interest.

Examples
use tokio::io::Interest;

assert!(Interest::READABLE.is_readable());
assert!(!Interest::WRITABLE.is_readable());

let both = Interest::READABLE | Interest::WRITABLE;
assert!(both.is_readable());

Returns true if the value includes writable interest.

Examples
use tokio::io::Interest;

assert!(!Interest::READABLE.is_writable());
assert!(Interest::WRITABLE.is_writable());

let both = Interest::READABLE | Interest::WRITABLE;
assert!(both.is_writable());

Add together two Interest values.

This function works from a const context.

Examples
use tokio::io::Interest;

const BOTH: Interest = Interest::READABLE.add(Interest::WRITABLE);

assert!(BOTH.is_readable());
assert!(BOTH.is_writable());
