Overview

A Prism interface's class that provides a fixed Prism::ParseLexResult instead of parsing.

This class implements the parse_lex method to return a preparsed Prism::ParseLexResult rather than parsing the source code. When the parse result is already available externally, such as in Ruby LSP, the Prism parsing process can be bypassed.
