Enum CompactionError 

#[non_exhaustive]
pub enum CompactionError {
    NotEnoughHistory,
    SummarizationFailed(String),
}

Failure surface of CompactionStrategy::compact (and therefore of History::compact_if_needed).

The façade Conversation::run / Conversation::stream wraps this in EngineError::Context when compaction fails mid-run.

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.

NotEnoughHistory

History has fewer messages than preserve_n_last, so there is nothing the strategy can drop. Indicates a configuration bug rather than a transient failure: raise the budget or lower HistoryBuilder::preserve_n_last.

SummarizationFailed(String)

A strategy that calls a ailoop_core::CompletionModel (notably SummarizeStrategy) failed to produce a summary. The original error is rendered as a string to keep CompactionError a non-generic, object-safe enum usable behind Box<dyn CompactionStrategy>.

Trait Implementations

impl Debug for CompactionError

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

Formats the value using the given formatter.

impl Display for CompactionError

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

Formats the value using the given formatter.

impl Error for CompactionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
