Struct CompactionConfig 

pub struct CompactionConfig {
    pub provider: String,
    pub model: String,
    pub system_prompt: Option<String>,
    pub user_prompt_template: Option<String>,
    pub max_summary_tokens: usize,
    pub temperature: f32,
}

Configuration for LLM-based compaction.

When a Compacting region hits its threshold, it sends content to an LLM for summarization. This config controls which LLM is used and how the summarization prompt is constructed.

Fields

provider: String

Provider to use for compaction (e.g., “anthropic”, “openai”)

model: String

Model to use (e.g., “claude-sonnet-4-6”, “gpt-5.4-mini”)

system_prompt: Option<String>

Custom system prompt for compaction (None = use default)

user_prompt_template: Option<String>

Custom user prompt template. Use {content} as placeholder for region content, {region_name} for the region name.

max_summary_tokens: usize

Max tokens for the summary response

temperature: f32

Temperature (lower = more deterministic)

Implementations

impl CompactionConfig

pub fn system_prompt(&self) -> &str

Get the system prompt, using the default if none is configured.

pub fn user_prompt(&self, content: &str, region_name: &str) -> String

Get the user prompt, substituting {content} and {region_name} placeholders.
