Crate protobuf_to_json 

protobuf-to-json

A parser that converts arbitrary protobuf data to json

Features

• No schema required
• Use field number as json key
• Configurable bytes encoding (base64, hex, byte array, etc.)
• Guess length-delimited value types (string, nested message, bytes)

Limitations

• Length-delimited value type is guessed based on content. It may not always be correct.
• Repeated fields (with the same field number) may not be grouped into arrays when only one field is parsed.

Examples

use protobuf_to_json::Parser;
use hex_literal::hex;
use serde_json::json;

let data = hex!("0d1c0000001203596f751a024d65202b2a0a0a066162633132331200");
let parser = Parser::new();
let json = parser.parse(&data).unwrap();
let expected = json!({
    "1": 28,
    "2": "You",
    "3": "Me",
    "4": 43,
    "5": {
        "1": "abc123",
        "2": ""
    }
});
assert_eq!(json, expected);
