    Unauthorized(String),
    Forbidden(String),
    Di(String),
    Routing(String),

Framework-wide error type.

Variants

Http(String)

Status(u16, String)

Unauthorized(String)

Forbidden(String)

Di(String)

Routing(String)

Serialization(Error)

Internal(String)

Message(String)

Validation(String)

Validation error with user-readable message.

NotFound(String)

Resource not found.

Conflict(String)

Optimistic concurrency or state conflict.

PayloadTooLarge(String)

Request body (or one uploaded file) exceeded the configured limit.

UnsupportedMediaType(String)

Request content type is not supported by the target endpoint.

Problem(Box<ProblemDetails>)

A fully-formed problem response (validation, binding failure).

Carried as-is instead of being flattened into a message so the host can write the status and the extension members (errors) verbatim.

Implementations

impl Error

pub fn status_code(&self) -> u16

Map the error to an appropriate HTTP status code.

Used by the built-in exception middleware to produce well-formed HTTP error responses.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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(source: Error) -> Error

Converts to this type from the input type.
