Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Read

Wait for more input. Output pushed in this call is not sent: return Write (or Close) to flush it first.

Write

Flush pending output, then on_writable.

Park

No reads, no idle timer, until a completion or the park deadline.

Fields

until: Option<Instant>

The deadline; None uses the park timeout.

Close

Graceful: flush, FIN, bounded linger.

Abort

RST now.
