Struct Policy 

pub struct Policy {
    pub defaults: Defaults,
    pub target: BTreeMap<String, TargetPolicy>,
    pub flows: Option<FlowsPolicy>,
    pub journal: Option<JournalLocation>,
    pub telemetry: Option<TelemetryPolicy>,
}

The whole keel.toml document (contracts/policy.schema.json), typed.

deny_unknown_fields at every object level (here and on the layer structs) makes a typo’d or unknown key a configuration error (KEEL-E001 with the exact path via serde_path_to_error), honoring the frozen schema’s additionalProperties: false and E001’s “an unknown key was used” — instead of the previous silent drop that ran the target on defaults the user never asked for.

Fields

defaults: Defaults

target: BTreeMap<String, TargetPolicy>

flows: Option<FlowsPolicy>

journal: Option<JournalLocation>

Journal location (schema-validated), honored by the real core at configure time (see JournalLocation).

telemetry: Option<TelemetryPolicy>

Telemetry config (schema-validated); otlp_endpoint is honored by native front ends (env still wins), console is not yet wired — see TelemetryPolicy.

Implementations

impl Policy

pub fn resolve(&self, target: &str) -> ResolvedPolicy

impl Policy

pub fn resolve_target( &self, method: &str, host: &str, scheme: Option<&str>, port: Option<u16>, path: Option<&str>, ) -> String

The policy target key for one outbound request. See the module-level precedence comment above OUTBOUND_METHODS for the four tiers.

pub fn known_llm_hosts() -> Vec<(&'static str, &'static str)>

Every host the LLM host map (tier 1 of resolve_target’s precedence) knows about, as (host, provider) pairs — the enumeration twin of resolve_target‘s single-lookup form. Not tied to any policy instance: the map is a hardcoded constant, identical for every Policy. Lets front-end packs’ targets() (consumed by keel doctor/keel init documentation output) enumerate every known LLM provider host without holding their own copy (issue #49). Vertex’s REGIONAL endpoints are matched by suffix (VERTEX_REGIONAL_SUFFIX), not enumerated here — there is no fixed list of regions to list.

Trait Implementations
