Struct Error 

pub struct Error { /* private fields */ }

Error returned by typed provider handlers and runtime helpers.

Implementations

impl Error

pub fn new(message: impl Into<String>) -> Self

Creates an error without an explicit HTTP status code override.

pub fn with_status(status: u16, message: impl Into<String>) -> Self

Creates an error with an explicit HTTP status code.

pub fn bad_request(message: impl Into<String>) -> Self

Creates a 400 Bad Request error.

pub fn internal(message: impl Into<String>) -> Self

Creates a 500 Internal Server Error.

pub fn not_found(message: impl Into<String>) -> Self

Creates a 404 Not Found error.

pub fn unimplemented(message: impl Into<String>) -> Self

Creates a 501 Not Implemented error.

pub fn status(&self) -> Option<u16>

Returns the HTTP status code that should be used for this error, when one was supplied.

pub fn message(&self) -> &str

Returns the human-readable error message.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Infallible> for Error

fn from(_value: Infallible) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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.
