Struct MockError

pub struct MockError {
    pub code: StatusCode,
    source: Option<Box<MockError>>,
}

A mock error mainly for test.

Fields

code: StatusCode

source: Option<Box<MockError>>

Implementations

impl MockError

pub fn new(code: StatusCode) -> MockError

Create a new MockError without backtrace.

pub fn with_source(source: MockError) -> MockError

Create a new MockError with source.

Trait Implementations

impl Debug for MockError

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

Formats the value using the given formatter.

impl Display for MockError

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

Formats the value using the given formatter.

impl Error for MockError

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 ErrorExt for MockError

fn status_code(&self) -> StatusCode

Map this error to StatusCode.

fn as_any(&self) -> &dyn Any

Returns the error as Any so that it can be downcast to a specific implementation.

fn output_msg(&self) -> String

where Self: Sized,

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

where Self: Sized,

Find out root level error for nested error

impl StackError for MockError

fn debug_fmt(&self, _: usize, _: &mut Vec<String>)

fn next(&self) -> Option<&dyn StackError>

fn last(&self) -> &dyn StackError

where Self: Sized,

fn transparent(&self) -> bool

Indicates whether this error is “transparent”, that it delegates its “display” and “source” to the underlying error. Could be useful when you are just wrapping some external error, AND can not or would not provide meaningful contextual info. For example, the DataFusionError.
