Type Alias CommandHandler 

type CommandHandler = fn(&mut Server, Entity, Entity, Vec<String>, &ServerChatCommand) -> Result<(), Content>;

Handler function called when the command is executed.

Arguments

• &mut Server - the Server instance executing the command.
• EcsEntity - an Entity corresponding to the player that invoked the command.
• EcsEntity - an Entity for the player on whom the command is invoked. This differs from the previous argument when using /sudo
• Vec<String> - a Vec<String> containing the arguments of the command after the keyword.
• &ChatCommand - the command to execute with the above arguments – Handler functions must parse arguments from the the given String (parse_args! exists for this purpose).
