Struct Parse 

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

The result of parsing: a syntax tree and a collection of errors.

This type is designed to be stored in Salsa databases as it contains the thread-safe GreenNode instead of the non-thread-safe SyntaxNode.

Implementations

impl<T> Parse<T>

pub fn new(green: GreenNode, errors: Vec<ErrorInfo>) -> Self

Create a new Parse result from a GreenNode and errors

pub fn green(&self) -> &GreenNode

Get the green node (thread-safe representation)

pub fn errors(&self) -> &[ErrorInfo]

Get the syntax errors

pub fn ok(&self) -> bool

Check if there are any errors

pub fn to_result(self) -> Result<T, Error>

where T: AstNode<Language = Lang>,

Convert to a Result, returning the tree if there are no errors

pub fn tree(&self) -> T

where T: AstNode<Language = Lang>,

Get the parsed syntax tree

Returns the tree even if there are parse errors. Use errors() or ok() to check for errors separately if needed.

pub fn syntax_node(&self) -> SyntaxNode<Lang>

Get the syntax node

impl Parse<Makefile>

pub fn parse_makefile(text: &str) -> Self

Parse makefile text, returning a Parse result

impl Parse<Rule>

pub fn parse_rule(text: &str) -> Self

Parse rule text, returning a Parse result

pub fn to_rule_result(self) -> Result<Rule, Error>

Convert to a Result, extracting a single rule from the makefile

Trait Implementations

impl<T: Clone> Clone for Parse<T>

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

Returns a duplicate 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.
