Struct Response 

pub struct Response<T> { /* private fields */ }

A response message with initial application metadata.

This envelope does not represent terminal gRPC status or trailing metadata. Those belong to the RPC stream lifecycle.

Implementations

impl<T> Response<T>

pub fn new(message: T) -> Response<T>

Wraps a message with empty initial metadata.

pub const fn from_parts(metadata: Metadata, message: T) -> Response<T>

Combines initial application metadata and a message.

pub const fn metadata(&self) -> &Metadata

Borrows the initial application metadata.

pub const fn metadata_mut(&mut self) -> &mut Metadata

Mutably borrows the initial application metadata.

pub const fn get_ref(&self) -> &T

Borrows the response message.

pub const fn get_mut(&mut self) -> &mut T

Mutably borrows the response message.

pub fn into_parts(self) -> (Metadata, T)

Consumes the envelope, returning initial metadata and the message.

pub fn map<U>(self, transform: impl FnOnce(T) -> U) -> Response<U>

Transforms the message while preserving initial application metadata.
