--- Function that checks if the event matches the name.
---
--- An event matches name when its \`\`base_name\`\` or \`\`name\`\` is equal to the \`\`name\`\` argument or when \`\`{base_name}.{name}\`\` is equal to the \`\`name\`\` argument.
--- 
--- For example, using either \`\`Message\`\` or \`\`Discord.Message\`\` as name would match a Discord Message event.
---
--- **Note that this function is case-insensitive and internally converts all strings to lowercase.**
--- @param pat string The name to match against.
--- @param event Primitives.Event The event to check.
--- @return boolean True if the event matches the name, false otherwise.
function doesEventMatch(pat: string, event: Primitives.Event) end

--- Simple helper method that calls \`\`callback\`\` when the event matches the name. See \`\`doesEventMatch\`\` for more information
--- on how the name is matched.
---
--- @param event Primitives.Event The event to listen for.
--- @param pats string | {string} The name or list of names to match against.
--- @param callback function The callback to run when the event matches the name. The callback will receive the event as an argument.
--- @return nil
