element_51.model

Records for node types and graphs.

Every record is immutable and refuses unknown fields. The JSON these produce is the format the browser layer reads, so field names are a contract with rust/element-51-core/src/model.rs.

Functions

can_link(source, target)	Whether an output of type source may feed an input of type target.
find_input(node_type, name)	Find the input name of a node type, rows that grow included.
value_fits(value, kind)	Whether value is something a port of type kind can carry.
variadic_index(variadic, name)	Read the row number from a port name.

Classes

Graph(*, nodes, links)	The nodes and links the user has built.
Link(*, source, target)	A link from an output port to an input port.
Model()	Base for every record in this project: immutable, no unknown fields.
NodeType(*, name, inputs, outputs[, ...])	The shape of a node: its name and its ports, in drawing order.
PlacedNode(*, id, node_type, x, y[, values, ...])	A node placed in the graph.
Port(*, name, kind)	One input or output of a node type.
PortRef(*, node, port)	One end of a link: a port on a node in the graph.
PortType(*values)	The type of a port.
Variadic(*, prefix, kind)	A node type whose inputs grow as they are linked.
