Struct CustomizeNamesGenerator 

pub struct CustomizeNamesGenerator {
    pub registry: Weak<ArcSwap<ModeRegistry>>,
    pub config: Arc<ConfigRegistry>,
}

gen:customize – candidates for :customize <name>. Merges two sources:

• Every group declared via the groups! macro (GROUP_DECLS distributed slice) – bare names like editor, display, lsp.
• Every registered mode – names ending in -mode like lsp-completion-mode, text-mode.
• Every plugin option namespace in the live [ConfigRegistry] – treesitter-context, and whatever else is loaded.

The :customize parser routes on the -mode suffix, so a single candidate set covers both forms. Same Weak discipline as ModesGenerator.

The third source exists because the first two are COMPILE-time slices. A plugin registers its options at runtime, so a decl-only candidate set silently omits every plugin group – :customize <plugin> works but is never offered, which reads as “the feature isn’t there”. The config handle is a strong Arc (matching gen:options, which holds the same registry) because the registry outlives the completion registry rather than the other way round.

registry: Weak<ArcSwap<ModeRegistry>>

config: Arc<ConfigRegistry>

Trait Implementations

impl CandidateGenerator for CustomizeNamesGenerator

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.
