Crate etdl_parser 

Parsing for the Event Tree Definition Language (ETDL).

etdl-parser reads .etdl documents — the declarative, design-time DSL for reliability-aware event-driven microservices defined by IEC 62502:2010 (event tree analysis) and IEC 61025:2006 (fault tree analysis) — and resolves their references into AsyncAPI 3.0 contracts.

Features

• ast — full document AST with manual Deserialize (supports legacy eventTree and x-* extension fields)
• ecel — the Event-tree Condition Expression Language (ECEL), a typed, side-effect-free expression language for barrier branch conditions
• asyncapi — AsyncAPI 3.0 document loading and a schema-introspecting registry
• jsonptr — RFC 6901 JSON Pointer resolution for onFailureProbabilitySource and other in-document references

Example

use etdl_parser::parse_document_from_file;
use std::path::Path;

let doc = parse_document_from_file(Path::new("order-fulfillment.etdl"))?;

Modules

ast

asyncapi

ecel

jsonptr

semantic

LSP-style semantic endpoints over an ETDL document (completions, hover, go-to-definition, find-references, document symbols, formatting).

spanned

Source-position tracking for ETDL documents.

Functions

load_asyncapi_imports

parse_document

parse_document_from_file

parse_document_raw

Like parse_document but preserves the underlying serde_yaml error so callers can recover a source position via serde_yaml::Error::location.
