Function task_configuration 

pub fn task_configuration(workspace: &Workspace, task: &Task) -> Value

What a task’s key holds of its project’s configuration beside its definition and resolved inputs: the project’s keyed settings, such as its root, the paths its outputs resolve to, which {project.*} tokens can read from anywhere in the configuration, and all of the configuration when a forwarded argument holds such a token, as the task reads it then.
