Struct MetadataManager 

pub struct MetadataManager { /* private fields */ }

High-performance metadata manager

Implementations

impl MetadataManager

pub fn new() -> Self

Create a new metadata manager

pub fn add_source(&self, source: MetadataSource)

Add a metadata source

pub async fn fetch_all(&self) -> Result<FetchStats>

Fetch all metadata from configured sources

pub fn add_custom_functions_from_json(&self, json: &str) -> Result<usize>

pub fn remove_custom_functions(&self)

pub fn add_custom_functions_from_json_file( &self, path: impl AsRef<Path>, ) -> Result<usize>

Load custom-functions JSON from a file on disk and register every entry.

The file must be an array of Function objects — the format produced by [generate_custom_functions_json_to_file].

pub fn generate_custom_functions_json( &self, folder: impl AsRef<Path>, ) -> Result<String>

Scan folder (and all sub-folders) for *.js / *.ts files, extract every custom function found via regex-based heuristics, and return a pretty-printed JSON string of Function objects.

Intended as a one-time build / CLI step. Save the result to a file and load it at LSP startup with [add_custom_functions_from_json_file] — no source parsing is needed at runtime.

The output is directly consumable by [add_custom_functions_from_json].

pub fn generate_custom_functions_json_to_file( &self, folder: impl AsRef<Path>, output_path: impl AsRef<Path>, ) -> Result<usize>

Like [generate_custom_functions_json] but writes the output directly to output_path, creating parent directories as needed.

Returns the number of functions written.

pub fn get_exact(&self, name: &str) -> Option<Arc<Function>>

Get function by exact name (case-insensitive)

pub fn get_prefix(&self, text: &str) -> Option<(String, Arc<Function>)>

Get the longest registered function name that is a prefix of text, matching strictly from the start of text.

pub fn get(&self, name: &str) -> Option<Arc<Function>>

Get function: tries exact match first, then prefix match from the start.

Use get_exact when you need strict lookup (e.g. bracketed calls).

pub fn get_with_match(&self, name: &str) -> Option<(String, Arc<Function>)>

Get function with match info (matched key + Arc)

pub fn get_many(&self, names: &[&str]) -> Vec<Option<Arc<Function>>>

Get multiple functions

pub fn get_completions(&self, prefix: &str) -> Vec<Arc<Function>>

Get completions for a prefix

pub fn all_functions(&self) -> Vec<Arc<Function>>

Get all functions

pub fn get_enum(&self, name: &str) -> Option<Vec<String>>

Get enum values

pub fn all_enums(&self) -> HashMap<String, Vec<String>>

Get all enums

pub fn get_event(&self, name: &str) -> Option<Event>

Get event by name

pub fn all_events(&self) -> Vec<Event>

Get all events

pub fn function_count(&self) -> usize

Get function count

pub fn enum_count(&self) -> usize

Get enum count

pub fn event_count(&self) -> usize

Get event count

pub fn clear(&self)

Clear all metadata

impl MetadataManager

pub fn export_cache(&self) -> MetadataCache

pub fn import_cache(&self, cache: MetadataCache) -> Result<()>

pub fn cache_to_json(&self) -> Result<String>

pub fn cache_from_json(&self, json: &str) -> Result<()>

impl MetadataManager

pub fn save_cache_to_file(&self, path: impl AsRef<Path>) -> Result<()>

pub fn load_cache_from_file(&self, path: impl AsRef<Path>) -> Result<()>

Trait Implementations

impl Default for MetadataManager

fn default() -> Self

Returns the “default value” for a type.
