Yaup - Yet Another URL Params crate

Serialize your structures as query parameters. I made this crate because I didn't find anything that matched the structure of the query parameters used in Meilisearch.

Specificities of this query parameters format:

• The crate writes the initial ? if there are parameters to send.
• You can only serialize structures that follow a "key-value" shape, like structures, HashMap, BTreeMap, etc.
• Sequences (arrays, vectors, tuples, etc) are comma-separated. { doggo: vec!["kefir", "echo"] } serialize as ?doggo=kefir,echo.
• Empty and null values are not ignored. { doggo: Vec::new(), catto: None } serialize as ?doggo=&catto=null.
• Return an error if you try to serialize a structure with multiple levels of key-value structures (i.e., an object containing a HashMap for example).

Example

#[derive(Debug, serde::Serialize)]
enum Filter { New, Registered, Blocked }

#[derive(Debug, serde::Serialize)]
struct Params {
    cursor: Option<usize>,
    per_page: Option<usize>,
    username: String,
    filter: Vec<Filter>,
}

let params = Params {
    cursor: Some(42),
    per_page: None,
    username: String::from("tamo"),
    filter: vec![Filter::New, Filter::Blocked],
};
assert_eq!(
    yaup::to_string(&params).unwrap(),
    "?cursor=42&per_page=null&username=tamo&filter=New,Blocked"
);

Thanks

This was originally a fork of serde_url_params which is still maintained. Thanks, boxdot, for the initial code.

Everything has been rewritten from scratch for the v0.3.0.
