Variants

Ok = 0

The operation completed successfully.

Cancelled = 1

The operation was cancelled.

Unknown = 2

Unknown error.

InvalidArgument = 3

Client specified an invalid argument.

DeadlineExceeded = 4

Deadline expired before operation could complete.

NotFound = 5

Some requested entity was not found.

AlreadyExists = 6

Some entity that we attempted to create already exists.

PermissionDenied = 7

The caller does not have permission to execute the specified operation.

ResourceExhausted = 8

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.

OutOfRange = 11

Operation was attempted past the valid range.

Unimplemented = 12

Operation is not implemented or not supported.

Internal = 13

Internal error.

Unavailable = 14

The service is currently unavailable.

DataLoss = 15

Unrecoverable data loss or corruption.

Unauthenticated = 16

The request does not have valid authentication credentials

Implementations

impl Code

pub fn from_http(http_code: StatusCode) -> Code

Returns the gRPC equivalent of http::StatusCode.

Loosely based on https://github.com/grpc/grpc/blob/master/doc/http-grpc-status-mapping.md with the following changes:

• http::StatusCode::NOT_FOUND => Code::NotFound (instead of Code::Unimplemented)
• http::StatusCode::UNPROCESSABLE_ENTITY => Code::InvalidArgument (instead of Code::Unknown)
• http::StatusCode::NOT_IMPLEMENTED => Code::Unimplemented (instead of Code::Unknown)
• http::StatusCode::INTERNAL_SERVER_ERROR => Code::Internal (instead of Code::Unknown)
• http::StatusCode::OK => Code::Ok (instead of Code::Unknown)

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

Get description of this Code.

pub fn to_header_value(self) -> HeaderValue

Returns http::HeaderValue representation.

Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Code

impl Debug for Code

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

Formats the value using the given formatter.

impl Display for Code

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

Formats the value using the given formatter.

impl Eq for Code

impl From<StatusCode> for Code

fn from(value: StatusCode) -> Self

Converts to this type from the input type.

impl Hash for Code

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Code

fn eq(&self, other: &Code) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
