Struct Status 

pub struct Status {
    pub code: Code,
    pub message: String,
    pub metadata: Metadata,
}

A terminal gRPC status. Trailing metadata rides along, because a server that fails is often the one with the most to say about why.

Fields

code: Code

message: String

metadata: Metadata

Implementations

impl Status

pub fn new(code: Code, message: impl Into<String>) -> Status

pub fn unavailable(message: impl Into<String>) -> Status

A transport-level failure: the call could not be carried. gRPC’s status for that is UNAVAILABLE, never UNKNOWN — UNKNOWN means the server said something we could not interpret.

pub fn is_ok(&self) -> bool

pub fn from_headers(headers: &HashMap<String, String>) -> Option<Status>

Read grpc-status / grpc-message out of a header or trailer block. Returns None when there is no grpc-status at all, which is how the caller tells “no trailers yet” from “trailers said OK”.

Trait Implementations

impl Clone for Status

fn clone(&self) -> Status

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Status

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

Formats the value using the given formatter.

impl Display for Status

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

Formats the value using the given formatter.

impl Error for Status

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
