Method get_code

src/context/builder.rs:97–100

Reads the source file and extracts the code for a node. Returns `None` if the file cannot be read or the line range is invalid. The `Result` wrapper is preserved for API stability with the previous signature; this method does not currently emit `Err`.

(&self, node: &Node)

    /// The `Result` wrapper is preserved for API stability with the previous
    /// signature; this method does not currently emit `Err`.
    pub fn get_code(&self, node: &Node) -> Result<Option<String>> {
        let mut cache: HashMap<String, Option<String>> = HashMap::new();
        Ok(self.get_code_cached(node, &mut cache))
    }

    /// Same as `get_code` but reads each file at most once per `cache`.
