}

An HTTP chaos / fault-injection profile for a host or expectation. Maps to the HttpChaosProfile schema. Captures the commonly-used fields; the model carries an extra map for any additional server-supported keys.

Fields

error_status: Option<u16>

HTTP error status code to return instead of the real response.

error_probability: Option<f64>

Probability (0.0–1.0) that a request triggers the error.

latency: Option<Delay>

Injected latency (a Delay).

connection_drop: Option<bool>

When true, drops the TCP connection without responding.

seed: Option<i64>

Fixed seed for deterministic probabilistic outcomes.

retry_after: Option<String>

Literal Retry-After header value returned with an injected error.

drop_connection_probability: Option<f64>

Probability (0.0–1.0) of dropping the TCP connection without responding.

succeed_first: Option<i64>

Let the first N requests succeed before chaos becomes active.

fail_request_count: Option<i64>

Number of requests to fail once chaos is active.

outage_after_millis: Option<i64>

Time-based outage: chaos activates this many ms after first match.

outage_duration_millis: Option<i64>

Time-based outage: chaos stays active this many ms then self-heals.

truncate_body_at_fraction: Option<f64>

Keep only this leading fraction (0.0–1.0) of the response body.

malformed_body: Option<bool>

Corrupt the response body so it fails to parse.

slow_response_chunk_size: Option<i64>

Dribble the response body in chunks of this many bytes.

slow_response_chunk_delay: Option<Delay>

Delay between slow-response chunks.

quota_name: Option<String>

Shared quota counter key.

quota_limit: Option<i64>

Max requests allowed per quota window.

quota_window_millis: Option<i64>

Quota fixed-window length in milliseconds.

quota_error_status: Option<u16>

Status returned when the quota is exceeded (default 429).

degradation_ramp_millis: Option<i64>

Ramp error/drop probabilities linearly over this many ms from first match.

graphql_errors: Option<bool>

Rewrite the response body as a GraphQL error envelope.

graphql_error_message: Option<String>

Message in errors[0].message of the GraphQL error envelope.

graphql_error_code: Option<String>

Value for errors[0].extensions.code.

graphql_nullify_data: Option<bool>

Whether data is null (default true) in the GraphQL error envelope.

extra: HashMap<String, Value>

Any additional fields the server supports that are not modelled above.

Implementations

impl HttpChaosProfile

pub fn new() -> Self

Create an empty chaos profile.

pub fn error_status(self, status: u16) -> Self

Set the error status code returned on fault.

pub fn error_probability(self, probability: f64) -> Self

Set the probability (0.0–1.0) of triggering the error.

pub fn latency(self, latency: Delay) -> Self

Set the injected latency.

pub fn connection_drop(self, drop: bool) -> Self

Drop the TCP connection without responding.

pub fn seed(self, seed: i64) -> Self

Set the deterministic seed.

Trait Implementations

impl Clone for HttpChaosProfile

fn clone(&self) -> HttpChaosProfile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HttpChaosProfile

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

Formats the value using the given formatter.

impl Default for HttpChaosProfile

fn default() -> HttpChaosProfile

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HttpChaosProfile

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HttpChaosProfile

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
