Function projection 

pub fn projection(
    tech: &str,
    forge: &str,
    repo: &str,
    scopes: &[String],
    workflow: Workflow,
    style: Option<Style>,
    nix: bool,
) -> Result<Vec<Entry>, RkError>

The whole payload projection for one pair.

Under the repo, scopes, workflow, style, and nix parameters: every snippet with its kind and rendered bytes, plus the routing block and the hook block — each a pure function of the recorded mode — sorted by destination. The Nix destinations project only where nix is on; a pair that ships none of them honestly projects the smaller product.

Errors

Returns the pair_files errors, and RkError::Other for a snippet destination the kind table does not classify, which is a defect in this binary.
