Using closures as component callbacks

[Spacerulerwill]

Is there any way to do this like in discord.py / discord.js. The reason I need to do this is because I need to somehow pass variables and data from my slash command callback to my select menu callback. If anyone knows how to use closures to achieve this, or another method I would be very grateful.

To clarify, I'm looking for a discord go equivalent to something like this in discord.py

async def command(ctx:Context):
    x = 5
    async def callback():
        # do something with x
        ...
    
    # we would create the component and add its callback here, and then add to message
