Enum Error 

#[non_exhaustive]
pub enum Error {
    BadRequest(String),
    Unauthorized(String),
    Forbidden(String),
    NotFound(String),
    Internal(String),
    Validation(Vec<FieldError>),
    Custom(u16, String),
}

Framework error type that maps to HTTP status codes

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.

BadRequest(String)

400 Bad Request

Unauthorized(String)

401 Unauthorized

Forbidden(String)

403 Forbidden

NotFound(String)

404 Not Found

Internal(String)

500 Internal Server Error

Validation(Vec<FieldError>)

422 Unprocessable Content with one entry per invalid field, rendered as {"error": "Validation failed", "status": 422, "fields": {"title": ["..."]}}. See Validator.

Custom(u16, String)

Custom status code + message

Implementations

impl Error

pub fn status_code(&self) -> u16

pub fn status(&self) -> StatusCode

The status as an http::StatusCode (invalid custom codes become 500)

pub fn message(&self) -> &str

impl Error

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

pub fn unauthorized(msg: impl Into<String>) -> Self

pub fn forbidden(msg: impl Into<String>) -> Self

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

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

pub fn validation(fields: Vec<FieldError>) -> Self

422 with the given invalid fields

pub fn fields(&self) -> &[FieldError]

The invalid fields of a Error::Validation, empty for other errors

pub fn custom(status: u16, msg: impl Into<String>) -> Self

Trait Implementations

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, f: &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<ClientError> for Error

fn from(e: ClientError) -> Self

Converts to this type from the input type.
