Function get_emoji

pub async fn get_emoji(
    collection: Collection<EmojiId>,
    role: &str,
    name: &str,
) -> Result<String, Error>

⚙️ Function: Retrieves a custom emoji string based on role and name from a MongoDB collection.

This asynchronous function searches a MongoDB collection for a custom emoji corresponding to a specific role and name. If found, it formats the emoji in a string compatible with Discord. If not found, it returns the provided name as a fallback.

Parameters:

• collection: A MongoDB Collection<EmojiId> containing the emoji mappings, where each document maps a role and name to an emoji ID.
• role: A string slice representing the role of the emoji (e.g., “position”, “champions”).
• name: A string slice representing the name of the emoji (e.g., “TOP”, “JUNGLE”, champion names).

Returns:

• Result<String, Error>: Returns a Result containing the formatted emoji string (if found) or the name as a fallback. In case of errors, it logs the error and returns the name.

Example:

This function can be used to retrieve custom emojis for roles or champions when creating embeds for Discord:

let emoji = get_emoji(collection_emojis, "position", "TOP").await?;
println!("The emoji for TOP is: {}", emoji);

Notes:

• The function creates a MongoDB filter to search for the emoji based on the role and name fields.
• If an emoji is found, it formats the emoji string in the form <:name:id>, which is recognized by Discord.
• If no emoji is found or an error occurs, the function returns the name string as a fallback and logs any errors encountered during the search.
