Crate lang_util

lang-util is a crate that implements utilities to parse and represent syntax trees. It also provides error formatting facilities for parsers using lalrpop.

This crate is tailored for use in the glsl-lang crate, but you may use its utilities for implementing your own language parsers:

• error: parsing error reporting module, with user-readable location information. Only available with the lalrpop feature enabled.
• node: AST node structure and display
• position: utilities for working with positions in strings
