Struct ParsedFile

pub struct ParsedFile<'a> { /* private fields */ }

A parsed source file with its tree-sitter parse tree and original source code.

Implementations

impl<'a> ParsedFile<'a>

pub fn parse( source_code: &'a str, parser: &mut Parser, ) -> Result<Self, ExtractionError>

Parse source code into a tree-sitter parse tree.

Parameters

• source_code - The source code to parse
• parser - A mutable reference to a configured tree-sitter parser

Returns

A new ParsedFile instance or an ExtractionError if parsing fails

pub fn root_node(&'a self) -> Node<'a>

Return the root node of the parse tree.

Returns

The root node of the parsed source file

pub fn render_node(&self, node: Node<'_>) -> Result<String, ExtractionError>

Return a tree-sitter node’s text content.

Parameters

• node - The tree-sitter node to render

Returns

The text content of the node or an ExtractionError if rendering fails

pub fn render(&self, range: Range<usize>) -> String

Return text content from a byte range in the source code.

Parameters

• range - The byte range to extract from the source code

Returns

The text content within the specified range

pub fn make_query(&self, query: &str) -> Result<Query, ExtractionError>

Create a new tree-sitter query from a query string.

Parameters

• query - The query string in tree-sitter query language

Returns

A compiled query or an ExtractionError if query creation fails

pub fn exec_query<'b>( &'b self, query: &'b Query, node: Node<'b>, cursor: &'b mut QueryCursor, ) -> QueryMatches<'b, 'b, &'b [u8], &'b [u8]>

Execute a tree-sitter query on a specific node.

Parameters

• query - The compiled tree-sitter query to execute
• node - The node to search within
• cursor - A mutable reference to a query cursor for tracking query state

Returns

An iterator over the query matches
