description
: A one-line description of the template, in CommonMark syntax. -
path
: The path of the directory to be copied. -
welcomeText
: A block of markdown text to display when a user initializes a new flake based on this template.

outputs = { self }: {
templates.rust = {
path = ./rust;
description = "A simple Rust/Cargo project";
welcomeText = ''
