Implementations

impl ClientError

pub fn message(&self) -> String

Returns the error message.

pub fn code(&self) -> Option<Code>

Returns the gRPC status code if this is a gRPC error.

pub fn status(&self) -> Option<&Status>

Returns the underlying gRPC Status if this is a gRPC error.

pub fn is_not_found(&self) -> bool

Returns true if this is a “not found” error.

pub fn is_precondition_failed(&self) -> bool

Returns true if this is a “precondition failed” error.

pub fn is_invalid_argument(&self) -> bool

Returns true if this is an “invalid argument” error.

pub fn is_connection_error(&self) -> bool

Returns true if this is a connection or transport error.

Trait Implementations

impl Debug for ClientError

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

Formats the value using the given formatter.

impl Display for ClientError

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

Formats the value using the given formatter.

impl Error for ClientError

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.

impl From<Error> for ClientError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Status> for ClientError

fn from(status: Status) -> Self

Converts to this type from the input type.
