Struct RateLimitConfig 

pub struct RateLimitConfig {
    pub responses_per_second: Option<u32>,
}

Response Rate Limiting (RRL) configuration.

BIND9 RRL throttles identical authoritative responses per client source prefix (an IPv4 /24 by default) to blunt DNS amplification and reflection attacks (threat model D1/D3). Because it applies only to authoritative answers and is scoped per source prefix, a modest per-second cap rarely affects legitimate clients.

Example

rateLimit:
  responsesPerSecond: 20

Fields

responses_per_second: Option<u32>

Maximum identical responses per second, per client source prefix.

Rendered as BIND9’s rate-limit { responses-per-second N; }. When unset, a conservative default of 15 is applied (RRL is on by default). Set to 0 to disable RRL entirely — no rate-limit block is emitted.

Trait Implementations

impl Clone for RateLimitConfig

fn clone(&self) -> RateLimitConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RateLimitConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RateLimitConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for RateLimitConfig

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 RateLimitConfig

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
