Struct Guard 

pub struct Guard { /* private fields */ }

The output-guard orchestrator. Cheap to share behind Arc.

Implementations

impl Guard

pub fn new(cfg: GuardConfig, scorer: Option<Box<dyn Scorer>>) -> Self

pub fn from_config(c: &PromptInjectionConfig) -> Result<Self, GuardError>

Build from config. In default builds the scorer is always None; if a model is configured, a warning is logged (the injection-model feature is required). Under the injection-model feature the configured ONNX model is loaded instead.

pub fn config(&self) -> &GuardConfig

pub fn tool_security_note(&self) -> String

A sentence describing, per override field, whether the agent’s security arg is currently honored (granted) or ignored (not granted). Appended to covered tools’ descriptions.

pub fn harden(&self, content: &str) -> Hardened

HIGH-strength cleaning for rover’s own inference. Always runs patterns plus the model (when loaded); ignores output-side allowlists/overrides (internal hardening is not bypassable).

pub fn assess( &self, url: &str, security: Option<&SecurityArg>, body: &str, ) -> Assessment

Scan + act on body. The caller renders the frontmatter (embedding Assessment.telemetry), then calls finish.

pub fn finish( &self, a: &Assessment, frontmatter: &str, body: &str, honor_drop: bool, ) -> String

Produce the final agent-facing content string. frontmatter is the already-rendered frontmatter (may be empty, e.g. for summarize). body is the final body to wrap: the acted-upon body for the direct path, or a summary on the summarize path. honor_drop is false on the summarize path — the returned body is a cleaned summary, so the strict-drop action on the raw body does not apply.

pub fn guard_metadata( &self, url: &str, security: Option<&SecurityArg>, fields: &mut [&mut String], ) -> MetadataGuard

Guard get_metadata field values in place. No wrapper (no document): scans each field, applies the level action to it, and returns aggregate telemetry plus a warning notice when anything was detected.

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

Formats the value using the given formatter.
