Crate ra_syntax

An experimental implementation of Rust RFC#2256 libsyntax2.0.

The intent is to be an IDE-ready parser, i.e. one that offers

• easy and fast incremental re-parsing,
• graceful handling of errors, and
• maintains all information in the source file.

For more information, see [the RFC][rfc#2265], or the working draft.

Re-exports

pub use crate::ast::AstNode;

Modules

ast

text_utils

utils

Utilities for simple uses of the parser.

Macros

Structs

SmolStr

A SmolStr is a string type that has the following properties:

SyntaxError

SyntaxNode

TextRange

A range in the text, represented as a pair of TextUnits.

WalkEvent

WalkeEvent describes tree walking process.

Traits
