Struct ElementsGenerator 

pub struct ElementsGenerator {
    pub registry: ThemeRegistryHandle,
}

gen:elements – one candidate per registered theme element / face. Walks [ThemeRegistry::element_names] so the candidate set follows the live registry (core elements plus any mode/plugin-contributed ones). Drives :describe-element <Tab> / :describe-face <Tab>.

Holds a strong ThemeRegistryHandle clone, mirroring ThemePickerSource (the theme registry is a host ServiceRegistry service that renderers read; nothing takes Arc::get_mut of it post-boot, so the Weak discipline the mode-registry generators use doesn’t apply here).

Fields

registry: ThemeRegistryHandle

Trait Implementations

impl CandidateGenerator for ElementsGenerator

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.
