The OpenFGA DSL Parser provides utilities for parsing DSL file string inputs into an AST representation, as well as transforming them into a JSON representation.
This library is meant to be a utility for services using OpenFGA for their authorization solution, but need a way to translate from their DSL to the JSON format the HTTP API expects. A Typescript library is available that does something similar, however this library aims to target Rust as well as be a base for other potential languages to bind to.
use openfga_dsl_parser::{json, Parser};
let input = "type group
relations
define member as self
type resource
relations
define writer as self
define reader as self but not writer";
let mut parser = Parser::new(input);
let doc = parser.parse_document()?;
let json = json::JsonTransformer::new(&doc).serialize();
