Struct Violation 

pub struct Violation {
    pub rule_id: String,
    pub severity: Severity,
    pub message: String,
    pub selector: String,
    pub viewport: ViewportKey,
    pub rect: Option<Rect>,
    pub dom_order: u64,
    pub fix: Option<Fix>,
    pub doc_url: String,
    pub metadata: IndexMap<String, Value>,
}

A single rule violation. This is the canonical unit of Plumb’s output.

Sort key for deterministic output is (rule_id, viewport, selector, dom_order).

Eq and Hash aren’t derived: metadata carries serde_json::Value, which is PartialEq only (floats). Engine dedup uses PartialEq.

Fields

rule_id: String

Stable rule identifier, e.g. spacing/hard-coded-gap.

severity: Severity

Severity — drives exit code.

message: String

Human-readable summary.

selector: String

CSS selector path to the offending node.

viewport: ViewportKey

Which viewport the violation was detected in.

rect: Option<Rect>

Bounding rect in viewport pixels, if applicable.

dom_order: u64

DOM document order — used as a stable tiebreaker.

fix: Option<Fix>

Proposed fix, if the rule has one.

doc_url: String

Documentation URL — plumb explain uses this for a deep link.

metadata: IndexMap<String, Value>

Arbitrary rule-specific metadata. Must round-trip through JSON.

Implementations

impl Violation

pub fn sort_key(&self) -> (&str, &str, &str, u64)

The deterministic sort key tuple. Public so downstream tools can compose it into their own orderings.

Trait Implementations

impl Clone for Violation

fn clone(&self) -> Violation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Violation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Violation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Violation

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Violation

fn eq(&self, other: &Violation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Violation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
