Configuration for AST integration

Fields

imports: Vec<String>

External modules to import (e.g., “crate::ast::*”)

result_type: Option<String>

Return type of the parse() function

span_type: Option<String>

External span type to use instead of generated Span

string_type: Option<String>

External string type to use instead of String (e.g., “JsString”)

error_type: Option<String>

External error type to use instead of generated ParseError

generate_parse_result: bool

Whether to generate the internal ParseResult enum (default: true)

generate_span: bool

Whether to generate the internal Span struct (default: true)

generate_parse_error: bool
