Enum Recovery 

pub enum Recovery {
    Retry,
    OmitLastMessage,
    Stop,
}

What a caller can do about a failed turn.

Failures that are a property of the history cannot be fixed by trying again — every later turn resends that history and fails the same way, which wedges the session. This is the top-level signal for those: it says whether the last user message has to come back out (see the chat adapter’s rewind operation) before the conversation can continue.

Variants

Retry

Nothing about the history is known to be at fault; resubmitting as-is may work (provider blip, refusal, malformed stream).

OmitLastMessage

The request is too big for the provider. Retrying unchanged fails identically — drop the last user message (typically the one carrying an oversized attachment) and the session can go on.

Stop

An execution contract was violated. Resolve it before issuing more work.

Trait Implementations

impl Clone for Recovery

fn clone(&self) -> Recovery

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Recovery

impl Debug for Recovery

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Recovery

impl PartialEq for Recovery

fn eq(&self, other: &Recovery) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
