Struct ResponsePolicy 

pub struct ResponsePolicy { /* private fields */ }

Per-application JSON success and error policy.

Mappers receive the current request, allowing envelopes to include request IDs or other context without process-global handlers. Values are fully serialized before headers are committed, so serialization failures become a deterministic HTTP 500 response.

Implementations

impl ResponsePolicy

pub fn new() -> Self

pub fn with_success_mapper<F>(self, mapper: F) -> Self

where F: Fn(&HttpRequest, Value) -> Value + Send + Sync + 'static,

pub fn with_error_mapper<F>(self, mapper: F) -> Self

where F: Fn(&HttpRequest, StatusCode, &str, &str, Option<Value>) -> Value + Send + Sync + 'static,

pub fn ok<T>(&self, request: &HttpRequest, value: T) -> HttpResponse

where T: Serialize,

pub fn error(&self, request: &HttpRequest, error: &ApiError) -> HttpResponse

pub fn respond<T>( &self, request: &HttpRequest, result: Result<T, ApiError>, ) -> HttpResponse

where T: Serialize,

pub fn grpc_error(&self, request: &HttpRequest, status: &Status) -> HttpResponse

Converts a Tonic status using the same status families as go-zero’s REST bridge.
