Module prototypes 

Hand-written prototype stubs for the data stage (data.extend).

These are not generated from prototype-api.json yet. They exist so mods can register common prototypes with typed struct literals; the codegen injects Factorio’s type = "..." discriminant from the Rust struct name.

Structs

Item

Minimal ItemPrototype for data.extend.

Recipe

Minimal RecipePrototype for data.extend.

RecipeIngredient

Item ingredient for a Recipe (type = "item" injected).

RecipeProduct

Item product for a Recipe (type = "item" injected).
