arch.diagrams

Package arch.diagrams · Version 0.1.0

Data-modelling primitives for entity / ER-style diagrams. Provides a table module kind and a column interface kind so you can draw schema and relationship diagrams — tables with typed columns and the keys linking them — in the same workspace as the rest of your architecture.

Widgets render tables in the familiar header-plus-rows shape. Import with use table, column from arch.diagrams.

Types

Type	Extends	Description
`column`	`interface`	A table column — its name is the column name and its `dtype` field the type annotation
`table`	`module`	Tabular structure — one row per `column` interface. The `dtype` field on each column becomes its type annotation, e.g. table Users { column id { dtype: “uuid” } column email { dtype: “text” } }
`operation`	`interface`	A class operation / method — a member of a class box
`class`	`module`	Two-compartment UML class box, e.g. class Account { column id { dtype: “uuid” } column balance { dtype: “money” } operation deposit { returns: “void” } operation withdraw { returns: “bool” } }
`member`	`interface`	An enum member — one named value of an enum box
`enum`	`module`	Enumeration, e.g. enum OrderStatus { member pending member shipped { value: 1 } member delivered { value: 2 } }
`note`	`module`	Annotation sticky, e.g. note Caveat { “Auth tokens expire after 15 min — refresh flow not shown.” }
`state`	`module`	A state-machine state — a node in a state diagram
`initial_state`	`state`	The initial pseudo-state a machine starts in — a small filled dot
`final_state`	`state`	A terminal state — the double-ring UML final marker
