Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

HttpResponse(Box<Error>, Backtrace)

Failed to prepare HTTP response.

InvalidBodyBase64(Box<DecodeError>, Backtrace)

Invalid base64 encoding for request body.

InvalidBodyJson(Box<Error<Error>>, Backtrace)

Failed to JSON deserialize request body.

InvalidBodyUtf8(Box<FromUtf8Error>, Backtrace)

Invalid UTF-8 encoding for request body.

InvalidHeaderUtf8(HeaderName, Box<dyn Error + Send + Sync + 'static>, Backtrace)

Invalid UTF-8 encoding for request header.

InvalidRequestPathParam

Failed to parse request path parameter.

Fields

param_name: Cow<'static, str>

Name of the parameter that failed to parse.

source: Option<Box<dyn Error + Send + Sync + 'static>>

Underlying error that occurred while parsing the param.

backtrace: Backtrace

Stack trace indicating where the error occurred.

InvalidRequestQueryParam

Failed to parse request query param.

Fields

param_name: Cow<'static, str>

Name of the parameter that failed to parse.

source: Option<Box<dyn Error + Send + Sync + 'static>>

Underlying error that occurred while parsing the param.

backtrace: Backtrace

Stack trace indicating where the error occurred.

MissingRequestBody(Backtrace)

Missing required request body.

MissingRequestHeader(Cow<'static, str>, Backtrace)

Missing required request header.

MissingRequestParam(Cow<'static, str>, Backtrace)

Missing required request param.

Panic(String, Backtrace)

Request handler panicked.

ToJsonResponse

Failed to serialize response body to JSON.

Fields

type_name: Cow<'static, str>

Name of the response body type that failed to serialize.

source: Box<Error<Error>>

Underlying error that occurred while serializing the response body.

backtrace: Backtrace

Stack trace indicating where the error occurred.

UnexpectedContentType(String, Backtrace)

Unexpected request Content-Type.

UnexpectedOperationId(String, Backtrace)

Unexpected operation ID.

Implementations

impl EventError

pub fn backtrace(&self) -> Option<&_Backtrace>

Return the backtrace associated with the error, if known.

pub fn name(&self) -> &str

Return the name of the error variant (e.g., InvalidBodyBase64).

Trait Implementations

impl Debug for EventError

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

Formats the value using the given formatter.

impl Display for EventError

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

Formats the value using the given formatter.

impl Error for EventError

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<&EventError> for HttpResponse

fn from(err: &EventError) -> HttpResponse

Build a client-facing HttpResponse appropriate for the error that occurred.

This function will set the appropriate HTTP status code (400 or 500) depending on whether the error is internal (500) or caused by the client (400). For client errors, the response body contains a human-readable description of the error and the Content-Type response header is set to text/plain. For internal errors, no response body is returned to the client.

impl From<EventError> for HttpResponse

fn from(err: EventError) -> HttpResponse

Converts to this type from the input type.
