Struct Parse

pub struct Parse<T> { /* private fields */ }

Parse is the result of the parsing: a syntax tree and a collection of errors.

Note that we always produce a syntax tree, even for completely invalid files.

Implementations

impl<T> Parse<T>

pub fn syntax_node(&self) -> SyntaxNode

pub fn errors(&self) -> Vec<SyntaxError>

impl<T: AstNode> Parse<T>

pub fn to_syntax(self) -> Parse<SyntaxNode>

Converts this parse result into a parse result for an untyped syntax tree.

pub fn tree(&self) -> T

Gets the parsed syntax tree as a typed ast node.

Panics

Panics if the root node cannot be casted into the typed ast node (e.g. if it’s an ERROR node).

pub fn ok(self) -> Result<T, Vec<SyntaxError>>

Converts from Parse<T> to Result<T, Vec<SyntaxError>>.

impl Parse<SyntaxNode>

pub fn cast<N: AstNode>(self) -> Option<Parse<N>>

impl Parse<SourceFile>

pub fn debug_dump(&self) -> String

pub fn reparse( &self, delete: TextRange, insert: &str, edition: Edition, ) -> Parse<SourceFile>

Trait Implementations

impl<T> Clone for Parse<T>

fn clone(&self) -> Parse<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Parse<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for Parse<T>

fn eq(&self, other: &Parse<T>) -> 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.
