Struct tower_http::classify::GrpcErrorsAsFailures

source · [−]

pub struct GrpcErrorsAsFailures { /* private fields */ }

Expand description

Response classifier for gRPC responses.

gRPC doesn’t use normal HTTP statuses for indicating success or failure but instead a special header that might appear in a trailer.

Responses are considered successful if

grpc-status header value is 0.
grpc-status header is missing.
grpc-status header value isn’t a valid String.
grpc-status header value can’t parsed into an i32.

All others are considered failures.

Implementations

source

impl GrpcErrorsAsFailures

source

pub fn new() -> Self

Create a new GrpcErrorsAsFailures.

source

pub fn make_classifier() -> SharedClassifier<Self>

Returns a MakeClassifier that produces GrpcErrorsAsFailures.

This is a convenience function that simply calls SharedClassifier::new.
