Struct Parser

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

Recursive Descent Parser for ECMAScript and TypeScript

See Parser::parse for entry function.

Implementations

impl<'a> Parser<'a>

pub fn new( allocator: &'a Allocator, source_text: &'a str, source_type: SourceType, ) -> Parser<'a>

Create a new Parser

Parameters

• allocator: Memory arena for allocating AST nodes
• source_text: Source code to parse
• source_type: Source type (e.g. JavaScript, TypeScript, JSX, ESM Module, Script)

pub fn with_options(self, options: ParseOptions) -> Parser<'a>

Set parse options

impl<'a> Parser<'a>

pub fn parse(self) -> ParserReturn<'a>

Main entry point

Returns an empty Program on unrecoverable error, Recoverable errors are stored inside errors.

See the module-level documentation for examples and more information.

pub fn parse_expression(self) -> Result<Expression<'a>, Vec<OxcDiagnostic>>

Parse a single Expression.

Example

use oxc_allocator::Allocator;
use oxc_ast::ast::Expression;
use oxc_parser::Parser;
use oxc_span::SourceType;

let src = "let x = 1 + 2;";
let allocator = Allocator::new();
let source_type = SourceType::default();

let expr: Expression<'_> = Parser::new(&allocator, src, source_type).parse_expression().unwrap();

Errors

If the source code being parsed has syntax errors.
