sif-parser

A complete, standalone implementation of the Structured Interchange Format (SIF) v1 -- parser, emitter, streaming protocol, packed binary encoding, and format conversion. Zero external dependencies.

Features

• Parsing -- parse SIF documents with full support for schemas, blocks, templates, sections, inline annotations, and CDC operations.
• Emitting -- produce well-formed SIF output from Document values.
• Streaming -- SIF Streaming Protocol v1 with multiplexing, schema evolution, flow control, and heartbeat.
• Packed binary -- compact binary encoding for SIF data.
• Format conversion -- convert between SIF and JSON, JSONL, and CSV.
• Type inference -- infer schemas and types from untyped data.

Quick Example

use sif_parser::{parse, Document};

let input = "\
#schema | id:int | name:str | active:bool
1 | alice | true
2 | bob   | false
";

let doc: Document = parse(input).unwrap();
assert_eq!(doc.blocks.len(), 1);
assert_eq!(doc.blocks[0].records.len(), 2);

Independence from forma

This crate is a standalone SIF parser with no dependency on the forma serialization framework. It can be used on its own wherever SIF parsing or generation is needed. The forma_sif crate builds on top of this one to provide forma trait integration.
