Struct SnippetRegistry 

pub struct SnippetRegistry { /* private fields */ }

Per-language store. Snippets index by every prefix they register (multi-prefix snippets register under each).

Implementations

impl SnippetRegistry

pub fn new() -> Self

pub fn insert(&mut self, language: &str, snippet: Snippet)

Insert a snippet for a given language. When the snippet has multiple prefixes, registers under each. Languages are matched verbatim against the host’s scope -> language mapping; future scope-expression support extends this.

pub fn lookup(&self, language: &str, prefix: &str) -> Vec<&Snippet>

Snippets matching prefix for language. Walks the per-language index then a * (any-language) index. Each snippet appears once even when its prefix slot has multiple registrations (different snippets sharing a prefix is allowed – popular for “if-else” vs “if” both triggering on if).

pub fn matching_prefix<'a>( &'a self, language: &str, query: &str, ) -> Vec<&'a Snippet>

Every snippet whose prefix STARTS with the given query (case-insensitive) for the given language. Used by the gen:snippet source to populate the completion popup – the host’s matcher takes over from there.

pub fn by_name(&self, name: &str) -> Option<&Snippet>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn languages(&self) -> Vec<&str>

Languages with at least one registered snippet.

pub fn meta_for_language(&self, language: &str) -> Vec<SnippetMeta>

Display-only metadata view – :list-snippets / :describe-snippet consume this without forcing a body clone.
