Struct FailedCompaction 

pub struct FailedCompaction {
    pub error: Error,
    pub llm_usage: TokenUsage,
}

A failed compaction attempt, carrying the provider-billed usage of any summarization LLM calls that were already made before the failure.

Surfaced by ContextCompactor::compact_history_with_usage so the agent loop can fold billed-but-wasted summarization spend into the run’s cumulative usage even when the history is left uncompacted (guardrail block, truncation-retry error, replace_history failure).

Fields

error: Error

Why the compaction attempt failed.

llm_usage: TokenUsage

Usage billed by summarization calls made before the failure (zero when the failure preceded any LLM call).
