Enum AppError

pub enum AppError {
    NotFound(String),
    InvalidInput(String),
    DbError(String),
    AuthError(String),
    AuthzError(String),
    ExternalServiceError(String),
    ConfigError(String),
    Internal,
    ServiceError(String),
}

A common application error type for use across services. Microservices can extend this by creating their own error types that convert to AppError.

Variants

NotFound(String)

InvalidInput(String)

DbError(String)

AuthError(String)

AuthzError(String)

ExternalServiceError(String)

ConfigError(String)

Internal

ServiceError(String)

Custom error variant that allows microservices to add their own errors

Implementations

impl AppError

pub fn status_code(&self) -> StatusCode

Map the error to an HTTP status code.

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

Create a custom service error

pub fn is_client_error(&self) -> bool

Check if error is client-side (4xx)

pub fn is_server_error(&self) -> bool

Check if error is server-side (5xx)

Trait Implementations

impl Debug for AppError

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

Formats the value using the given formatter.

impl Display for AppError

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

Formats the value using the given formatter.

impl Error for AppError

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<&str> for AppError

fn from(msg: &str) -> Self

Converts to this type from the input type.

impl From<String> for AppError

fn from(msg: String) -> Self

Converts to this type from the input type.

impl Serialize for AppError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
