Module model 

The architecture model every front-end produces and the emitter consumes.

Ids are segment lists (["playwright_rs", "server", "connection"]), which LikeC4 renders as playwright_rs.server.connection. The model keeps real names; mapping them to LikeC4 identifiers happens in the emitter, and Model::validate is what says two names would collide there.

Structs

Deployment

Deployment nodes and instances. Empty until an infrastructure front-end exists; it is here from day one because LikeC4 keeps a separate deployment model and retrofitting it would rework every front-end.

DeploymentInstance

DeploymentNode

Element

Model

What a front-end found, plus the externals the config adds.

Relation

Enums

ElementKind

RelationKind

Evidence for a relation, strongest first. Aggregation keeps the minimum, so the declared order is the precedence and must not be reordered.

Constants

RESERVED

Words likec4 1.59.3 refuses as an element id: every keyword token of its grammar (extracted from the language server bundle) plus this, it, true and false, each confirmed by validating a model with the word as a nested element. model, element, deployment and relationship are accepted and so are not here. A module named one of these gets a trailing _.

Functions

dotted

An id as LikeC4 renders it, before sanitizing: segments joined by ..

is_lineal

Whether one id is an ancestor of, a descendant of, or equal to the other. mod x; and pub use x::Y are structure, not coupling, so a relation between lineal elements is never recorded.

sanitize_id

The whole id as a LikeC4 identifier path.

sanitize_segment

One segment as a LikeC4 identifier: - and any other character outside [A-Za-z0-9_] become _, a leading digit gets a _ in front of it, and a RESERVED word gets one after it.

Type Aliases

Id

A fully qualified element id: crate, then module path.
