plumb-core

Deterministic design-system linter — rule engine and core types.

plumb-core is the foundation of the Plumb workspace. It defines the Rule trait, the violation model, the PlumbSnapshot representation, and the config schema. All output is byte-identical across runs by design.

Crate highlights

• Rule engine — register rules, run them against a snapshot, collect sorted violations.
• Snapshot types — PlumbSnapshot, SnapshotCtx, ElementNode, ComputedStyles, viewport definitions.
• Config — Config struct with serde + schemars support.
• No I/O, no async, no wall-clock — pure functions of (snapshot, config).
