Some resource has been exhausted.

§

FailedPrecondition = 9

The system is not in a state required for the operation’s execution.

§

Aborted = 10

The operation was aborted.

§

Implementations§

source§

impl Code

source

pub fn description(&self) -> &'static str

Get description of this Code.

fn make_grpc_request() -> tonic::Code {
    // ...
    tonic::Code::Ok
}
let code = make_grpc_request();
println!("Operation completed. Human readable description: {}", code.description());

If you only need description in println, format, log and other formatting contexts, you may want to use Display impl for Code instead.

source§

impl Code

source

pub fn from_i32(i: i32) -> Code

Get the Code that represents the integer, if known.

If not known, returns Code::Unknown (surprise!).

source

pub fn from_bytes(bytes: &[u8]) -> Code

Convert the string representation of a Code (as stored, for example, in the grpc-status header in a response) into a Code. Returns Code::Unknown if the code string is not a valid gRPC status code.
