Struct Context 

pub struct Context {
    pub request: GatewayRequest,
    pub response: GatewayResponse,
    pub message: HashMap<String, Value>,
    pub errors: Vec<GatewayError>,
}

Holds all state for one request as it travels through a policy graph.

Each plugin receives the context, may mutate any part of it, and passes it on through its success or error port. The engine sends response back to the client once graph execution finishes.

Fields

request: GatewayRequest

The inbound HTTP request as received by the listener (plugins may rewrite it before proxying).

response: GatewayResponse

The response being built; whatever is here when the graph finishes is sent to the client.

message: HashMap<String, Value>

Free-form key/value scratch space for passing data between nodes (e.g. auth claims).

errors: Vec<GatewayError>

Errors recorded by nodes; routing through a node’s error port appends here.

Implementations

impl Context

pub fn new(request: GatewayRequest) -> Self

Creates a fresh context for an inbound request.

The response starts empty with status_code == 0 (i.e. “unset”), and message/errors start empty.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

impl Debug for Context

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Context

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Context

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
