what data structure does model formula operator in R create? [closed]

The R Language Definition makes several mentions of the model formula operator, but fails to define or explain anything about the formula class.

I am having a hard time finding anything that documents the semantics of the ~ operator from either official or unofficial sources.

In particular, I am not interested in information like is provided in the formula function documentation ("An expression of the form y ~ model is interpreted as a specification that the response y is modelled by a linear predictor specified symbolically by model.") or usage scenarios, I'd like to understand what kind of data structure I am creating when using it and how I could inspect and dissect it on the REPL.
