QueryParams Derive

Rust custom derive to automatically implement serialization to http query params for arbitrary structs. A simple #[derive(QueryParams)] will generate a function to_query_params for your struct.

How it Works

#[macro_use]
extern crate query_params;

#[derive(QueryParams)]
struct PullRequestsParametersApi {
    page: i32,
    sort: bool,
    direction: String,
    state: Vec<String>,
    // .. other interesting fields ..
} 

fn main() {
    let pr = PullRequestsParametersApi {
        page: 2,
        sort: true,
        direction: "asc",
        state: vec!["open".to_string(), "closed".to_string()],
    }

    println!("{}", pr.to_query_params()); // => ?page=2&sort=true&direction=asc&state=open,closed
}

Get Started

It's as simple as two steps:

  1. Add query_params to your Cargo.toml
  • manually

  • or with cargo-edit:

    cargo add derive_builder

  1. Annotate your struct with #[derive(QueryParams)]

Disclaimer ❗

  • Tuple structs and unit structs are not supported as they have no field names.
