AbortIo

rama::io

Struct AbortIo 

pub struct AbortIo(/* private fields */);
Available on crate feature std only.
Expand description

Ends an I/O abortively: its peer sees a reset (a TCP RST, an HTTP/2 RST_STREAM, an HTTP/3 RESET_STREAM) instead of an orderly end of stream, and data not yet delivered may be discarded.

An I/O publishes it in its own Extensions store, so a lookup with Extensions::self_get_ref never reaches the handle of another I/O, such as the connection that multiplexes this stream. A relay calls it to reflect a failure of the opposite side (RFC 9113 §8.5, RFC 9114 §4.4); without it a relay can only close in order.

The reset is sent at once or, at the latest, when the I/O is dropped; built-in TCP streams reset on drop. Repeated calls are harmless. Share it through Extensions::self_get_arc and Extensions::insert_arc.

Implementations§

§

impl AbortIo

pub fn new(abort: impl Fn() + Send + Sync + 'static) -> AbortIo

Install the transport’s abort.

pub fn abort(&self)

Abort the I/O.

pub fn reflects(err: &Error) -> bool

Whether a relay reflects err of one side as a reset of both. A peer that stopped reading (BrokenPipe) or closed without TLS close_notify (UnexpectedEof, common in the wild) ended in order.
