Struct ModesGenerator 

pub struct ModesGenerator {
    pub registry: Weak<ArcSwap<ModeRegistry>>,
}

gen:modes – one candidate per registered mode. Walks ModeRegistry::iter_meta so the candidate set follows the runtime registry (built-in foundation modes plus any feature- crate register_*_modes additions).

Holds a Weak to the registry so the generator doesn’t keep the Arc alive past the App’s lifetime, and – the operational reason – so Arc::get_mut(&mut app.mode_registry) still succeeds in tests that need to register a test-only mode post-boot. Upgrade-on-demand: a dropped registry yields an empty candidate set (no panic).

Fields

registry: Weak<ArcSwap<ModeRegistry>>

Trait Implementations

impl CandidateGenerator for ModesGenerator

fn generate(&self, _ctx: &GenerateContext<'_>) -> Vec<RawCandidate>

fn cache_key(&self, _ctx: &GenerateContext<'_>) -> Option<CacheKey>

Optional cache key. When two contexts produce the same Some(key), the pipeline serves the second from cache. The query (prefix) is implicitly part of the key only if the generator includes it – many generators key on a registry version (cache covers all queries until the registry changes) and let the matcher do the per-query filtering.

fn cache_ttl(&self) -> Duration

Soft TTL for cache entries. After elapsing, the entry is regenerated on next access. Defaults to no expiry.
