Struct ParserRegistry 

pub struct ParserRegistry { /* private fields */ }

Registry of all full-AST parsers, keyed by protocol name.

Provides language detection by file extension and dispatches parse/emit operations to the appropriate language parser.

Implementations

impl ParserRegistry

pub fn new() -> Self

Create a new registry populated with all enabled language parsers.

The set of languages depends on which panproto-grammars feature flags are enabled. The default is group-core (GitHub’s top 10 languages). Use group-all for all 248 supported languages.

pub fn register(&mut self, parser: Box<dyn AstParser>)

Register a parser implementation.

pub fn detect_language(&self, path: &Path) -> Option<&str>

Detect the language protocol for a file path by its extension.

Returns None if the extension is not recognized (caller should fall back to the raw_file protocol).

pub fn parse_file( &self, path: &Path, content: &[u8], ) -> Result<Schema, ParseError>

Parse a file by detecting its language from the file path.

Errors

Returns ParseError::UnknownLanguage if the file extension is not recognized. Returns other ParseError variants if parsing fails.

pub fn parse_with_protocol( &self, protocol: &str, content: &[u8], file_path: &str, ) -> Result<Schema, ParseError>

Parse source code with a specific protocol name.

Errors

Returns ParseError::UnknownLanguage if the protocol is not registered.

pub fn emit_with_protocol( &self, protocol: &str, schema: &Schema, ) -> Result<Vec<u8>, ParseError>

Emit a schema back to source code bytes using the specified protocol.

Errors

Returns ParseError::UnknownLanguage if the protocol is not registered.

pub fn theory_meta(&self, protocol: &str) -> Option<&ExtractedTheoryMeta>

Get the theory metadata for a specific protocol.

pub fn protocol_names(&self) -> impl Iterator<Item = &str>

List all registered protocol names.

pub fn len(&self) -> usize

Get the number of registered parsers.

pub fn is_empty(&self) -> bool

Check if the registry is empty.

Trait Implementations

impl Default for ParserRegistry

fn default() -> Self

Returns the “default value” for a type.
