Struct RegexMatchStatement

#[non_exhaustive]
pub struct RegexMatchStatement {
    pub regex_string: String,
    pub field_to_match: Option<FieldToMatch>,
    pub text_transformations: Vec<TextTransformation>,
}

A rule statement used to search web request components for a match against a single regular expression.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

regex_string: String

The string representing the regular expression.

field_to_match: Option<FieldToMatch>

The part of the web request that you want WAF to inspect.

text_transformations: Vec<TextTransformation>

Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they're used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.

Implementations

impl RegexMatchStatement

pub fn regex_string(&self) -> &str

The string representing the regular expression.

pub fn field_to_match(&self) -> Option<&FieldToMatch>

The part of the web request that you want WAF to inspect.

pub fn text_transformations(&self) -> &[TextTransformation]

Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they're used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.

impl RegexMatchStatement

pub fn builder() -> RegexMatchStatementBuilder

Creates a new builder-style object to manufacture RegexMatchStatement.

Trait Implementations

impl Clone for RegexMatchStatement

fn clone(&self) -> RegexMatchStatement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RegexMatchStatement

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

Formats the value using the given formatter.

impl PartialEq for RegexMatchStatement

fn eq(&self, other: &RegexMatchStatement) -> 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.
