Struct CompressResult 

pub struct CompressResult {
    pub tokens_saved: u32,
    pub summary: Option<String>,
    pub archived: Vec<Message>,
    pub prefix_invalidated_at: Option<usize>,
}

Compression result returned by every compactor.

Fields

tokens_saved: u32

Tokens freed from the partition.

summary: Option<String>

Generated summary text if any.

archived: Vec<Message>

Messages drained/archived from the context.

prefix_invalidated_at: Option<usize>

Cache-aware (W1-1 step 2 / DoD #4): the earliest history-message index this op rewrote or removed — i.e. where it invalidates the prompt-cache prefix. None = prefix-safe (touched nothing). The pipeline folds the minimum across stages and surfaces it on the observation.
