Struct FilterEngine 

pub struct FilterEngine { /* private fields */ }

Engine that applies the 8-stage JSON compression pipeline.

The engine holds a reference to the shared Config and resolves per-tool filter rules on each call via Config::get_tool_rules.

Examples

let config = Arc::new(Config::from_upstream(&["npx", "some-mcp"], None).unwrap());
let engine = FilterEngine::new(config);
let filtered = engine.filter("list_merge_requests", r#"[{"iid":1,"title":"Fix"}]"#);

Implementations

impl FilterEngine

pub fn new(config: Arc<Config>) -> Self

Create a new filter engine with the given configuration.

Precompiles all regex transforms from defaults and per-tool rules.

pub fn config(&self) -> &Config

Access the underlying configuration.

pub fn filter(&self, tool_name: &str, raw: &str) -> String

Apply the full filter pipeline to a tool’s raw output string.

If raw is valid JSON, it is parsed and run through all 8 pipeline stages. If parsing fails, only plain-text truncation is applied. Responses exceeding 10 MB are truncated before parsing.
