iabgpp-rs

Rust implementation of the IAB Global Privacy Platform (GPP) consent string specification.

⚠️ This is work in progress.

Features

• Eager or lazy decoding of GPP sections
• Owning type (GPPString)
• Reference type (GPPStr)
• Read support for all current GPP sections

Usage example

Cargo.toml:

[dependencies]
iab-gpp = "0.1"

main.rs:

use std::error::Error;
use std::str::FromStr;
use iab_gpp::v1::GPPString;

fn main() -> Result<(), Box<dyn Error>> {
    let s = "DBABM~CPXxRfAPXxRfAAfKABENB-CgAAAAAAAAAAYgAAAAAAAA";
    let gpp_str = GPPString::from_str(s).expect("a valid GPP string");

    for &id in gpp_str.section_ids() {
        println!("Section id: {:?}", id);

        let section = gpp_str.decode_section(id).expect("a valid section");
        println!("Section: {:?}", &section);
    }
}

GPP Standard support

This crate intends to be in sync with the GPP specification, meaning that it should be able to read payloads with the versions specified here.

If the standard gets updated with new versions, this page should keep track of incompatibilities.

Legend:

• ✅ complete support
