Struct DocumentParserRegistry 

pub struct DocumentParserRegistry { /* private fields */ }

Registry that maps file extensions to DocumentParser implementations.

• Created with new(): includes PlainTextParser for all common formats.
• Created with empty(): no parsers at all (useful for overriding defaults).
• Later registrations override earlier ones for the same extension.

Implementations

impl DocumentParserRegistry

pub fn new() -> Self

Create a registry pre-loaded with PlainTextParser.

pub fn empty() -> Self

Create an empty registry (no parsers registered).

pub fn register(&mut self, parser: Arc<dyn DocumentParser>)

Register a parser. Later registrations win for the same extension.

pub fn find_parser(&self, path: &Path) -> Option<Arc<dyn DocumentParser>>

Find the parser responsible for path (extension lookup, then linear can_parse scan).

pub fn parse_file(&self, path: &Path) -> Result<Option<String>>

Parse path and return the extracted text.

Returns:

• Ok(Some(text)) — parsed successfully
• Ok(None) — no parser available, or file too large
• Err(_) — I/O or metadata failure (not a parse failure)

pub fn parsers(&self) -> &[Arc<dyn DocumentParser>]

All registered parsers (in registration order).

pub fn len(&self) -> usize

Number of registered parsers.

pub fn is_empty(&self) -> bool

Returns true if no parsers are registered.

Trait Implementations

impl Clone for DocumentParserRegistry

fn clone(&self) -> DocumentParserRegistry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for DocumentParserRegistry

fn default() -> Self

Returns the “default value” for a type.
