Small addition of an undocumented API, makes trying to get the corresponding Modrinth mod a whole lot easier.

• Relevant code
• Example response for the sodium mod

Could also consider adding the /download part of it

This is still a WIP, but I might as well open it already. V1 to V2 migration guide can be found here

• Routes have been corrected to account for the new naming (mod > project).
• Checked for feature parity with the API repo and added/renamed accordingly

To consider:

• The wording of comments, methods and structs is most likely going to need to be changed as mods are now called projects in preparation for modpack support
• permissions in TeamMember is defined here
• Using #[serde(deny_unknown_fields)] to catch inconsistencies earlier may be useful
• Re-export Bytes to avoid having to explicitly add it to the dependency list if not used anywhere else.

I'd want to see support added for using filters in the queries. Maybe something like the following could work to still keep the text based ones simple:

struct Query {}

impl From<String> for Query {}

And then some logic inside each function (get_mod, list_mods, etc) to handle the filters that are valid for the endpoint being reached.

This pull request implements the /search endpoint according to the Modrinth API Specification.

In order to implement said endpoint, a new helper method for HTTP GET was created, get_with_optional_query, since either meilisearch or labirinth doesn't handle the passing of empty optional queries (e.g &facets=[], &filters="", &version="", etc.), that method solves that function by filtering the key-value pairs that have a value of None out, and as such they aren't added to the request.

It also adds utilities for safely interacting with the facet api, FacetBuilder and ModrinthFacet.

This API is subject to change, since this is my first time writing rust code and I don't know what is idiomatic or not.

Corresponding to the current API specs (and I read it in the announcement channel of Modrinth's Discord) all old versions got their file hashes generated
