Struct CommandsGenerator 

pub struct CommandsGenerator;

gen:commands. Walks the CommandRegistry and emits one RawCandidate per registered CommandSpec. Filtering is deferred to the matcher; the generator returns the full set every time the cache misses.

Delimiter-form commands (ex:substitute, ex:global – SurfaceForm::Delimiter) are excluded: the user types those via :s/.../.../, :g/.../.../, :v/.../.../. Surfacing them as completion candidates is misleading because typing :ex:global would error with “use the delimiter form” – the keyword form is intentionally a hard-error redirect (DESIGN.md §B.2). They remain reachable through :describe-command / :apropos for introspection.

Trait Implementations

impl CandidateGenerator for CommandsGenerator

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.
