Struct CrsRule 

pub struct CrsRule {
    pub id: u32,
    pub severity: u8,

SEC-08 (#212): A single OWASP CRS-compatible WAF rule. Each rule has a numeric ID (CRS convention: 9xxxx), a severity level, a phase (1 = request headers, 2 = request body), a list of tags, a regex pattern, and the inspection targets to apply the pattern to. Rules are evaluated in order; matching rules add their severity to the request’s anomaly score. The request is blocked when the score exceeds the configured threshold.

Fields

id: u32

Unique rule ID (CRS convention: 9xxxx). Used for exclusions and logging.

severity: u8

Rule severity: 1 = critical, 2 = warning, 3 = notice, 4 = info. Higher severity contributes more to the anomaly score.

phase: u8

Evaluation phase: 1 = request headers (path, query, headers), 2 = request body. Default 1.

tags: Vec<String>

Tags for grouping and exclusion (e.g. “OWASP_CRS”, “SQL_INJECTION”).

pattern: String

The regex pattern to match against the target values.

targets: Vec<String>

Which request parts to inspect: “path”, “query”, “header”, “headers” (all selected headers), “body”. Default: [“path”, “query”].

transformations: Vec<String>

Optional list of transformations to apply before matching (e.g. “lowercase”, “url_decode”, “html_entity_decode”). Default: [].

Trait Implementations

impl Clone for CrsRule

fn clone(&self) -> CrsRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrsRule

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CrsRule

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for CrsRule

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 CrsRule

fn eq(&self, other: &CrsRule) -> 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 CrsRule

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
