Function get_champions

pub async fn get_champions(
    client: &Client,
    puuid: &str,
    region: &str,
    riot_api_key: &str,
) -> Result<Vec<HashMap<String, Value>>, Box<dyn Error + Send + Sync>>

⚙️ Function: Retrieves the top 10 champions for a player based on champion mastery.

This function sends a request to the Riot API to fetch the player’s top 10 champions based on their mastery score. The information returned includes champion mastery level and points for each champion.

Parameters:

• client: An instance of the reqwest::Client used to send HTTP requests.
• puuid: The player’s unique PUUID (Player Unique Identifier), used to identify the player in Riot’s systems.
• region: A string representing the region (e.g., euw1, na1, kr) where the player’s account is located.
• riot_api_key: The API key used to authenticate the request with the Riot API.

Returns:

• Result<Vec<HashMap<String, Value>>, Error>: A vector of HashMap objects, where each entry contains champion mastery details, or an error if the request fails.

⚠️ Notes:

• The function returns the top 10 champions based on mastery points, but this count can be adjusted in the API URL.
• The information includes each champion’s ID, mastery level, and mastery points.
• The function requires a valid puuid and region for the request to succeed.

Example:

let top_champions = get_champions(&client, "abcd1234-efgh5678-ijkl91011-mnop1213", "euw1", riot_api_key).await?;

The resulting top_champions vector will contain data like:

[
  {
    "championId": 157,
    "championLevel": 7,
    "championPoints": 500000
  },
  {
    "championId": 238,
    "championLevel": 6,
    "championPoints": 350000
  }
]
