Struct ParseTree

pub struct ParseTree { /* private fields */ }

A fully parsed feature file, with attached imports and a sourcemap.

As well as representing the entire AST, this type also allows mapping tokens and other spans back to a position in a particular source file.

This is cheap to clone, so it can be attached to diagnostics, allowing them to print themselves where needed.

Implementations

impl ParseTree

pub fn root(&self) -> &Node

The root node for this parse tree

pub fn typed_root(&self) -> Root

The root node, as typed AST node

pub fn source_map(&self) -> &SourceMap

Return a refernce to the source map

pub fn get_source(&self, id: FileId) -> Option<&Source>

Return the source for this id, if it exists in the source map

pub fn format_diagnostic(&self, err: &Diagnostic, colorize: bool) -> String

Generate a string suitable for presenting a Diagnostic to the user.

This associates the message with the appropriate source location and syntax highlighting.

Trait Implementations

impl Clone for ParseTree

fn clone(&self) -> ParseTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseTree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ParseTree

fn eq(&self, other: &ParseTree) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
