Feat: Crud operations completed #6
Conversation
This will be separate from the main binary as that will house the GUI in the future. `todo` will be just the CLI to interface with tasks.

It was just in the docs, can use just as it is tho.

Can this be avoided? Given that now there is a Display trait for Priority now

It was an error because of the custom type "enum" in database, which was not recognized by tokio as it needed to convert string to enum type and enum type to string, read from the cli.

if it's resolved this way, great. but i had to implement the same for Difficulty as well

Is the Display trait not enough?

I dont think so, because after the Display trait was implemented, i still got the error in the tokio while reading the enum value of difficulty

The underscore in _args specifies that it's an unused variable. If we're using it, remove the underscore.

Let's keep the deadline as NaiveDate; in hindsight, I don't see the time being useful for this since that's too much micro-management
