prima_bridge 0.29.0

//! Graphql Multipart example
//!
//! In this example there's the explanation on how to achieve a graphql call including multipart files.
//! Sadly this example doesn't work (not able to find a live example with multipart uploads).
//!
//! Run this to run the example:
//!
//! ```shell
//! cargo run --example graphql_multipart
//! ```
