Possible kinds of variables

[BenWeber42]

Here we list possible kinds of variables that we could encounter during the development of dusk. Taking possible future directions into account should help us design good answers to the challenges we face regarding kinds of variables.

Fields (+type: Real, single/double precision float, int, bool?)

• API Fields
• temporary Fields

Variables (+types)

• global (constexpr, runtime parameter)
• local

In the Vertical

• vertical iteration variable: usually k (or level)
• vertical interval boundary markers (k_flat, k_end, k_start)

Vertical Indirections

• absolute vertical offsets
• Int/KIndex Fields?

Horizontal Indirections

Neighborhood Variables

• constexpr aliases for short-cuts (diamond = Edge > Cell > Vertex)
• special neighborhoods (half_diamond)

Array-Like

• First-class support for weights (from reductions)
• Possibly support arrays?
• Vector Fields
