Struct ApplicationError 

pub struct ApplicationError {
    pub code: String,
    pub message: String,
    pub retryable: bool,
    pub remediation: String,
    pub details: Box<ApplicationErrorDetails>,
    /* private fields */
}

Error type surfaced by the application layer, carrying a stable code, remediation guidance, and structured source-specific details.

Fields

code: String

Stable, machine-readable error code.

message: String

Human-readable, redacted description of the failure.

retryable: bool

Whether retrying the operation might succeed.

remediation: String

Suggested remediation the caller can act on.

details: Box<ApplicationErrorDetails>

Structured details describing where the error originated.

Implementations

impl ApplicationError

pub fn new( code: impl Into<String>, message: impl Into<String>, retryable: bool, remediation: impl Into<String>, ) -> Self

Builds a generic ApplicationError from its core fields.

pub fn with_details(self, details: ApplicationErrorDetails) -> Self

Attaches structured details and returns the updated error.

pub fn private_diagnostics(&self) -> Option<&str>

Returns the internal diagnostics, which are never serialized to callers.

pub fn service_error_kind(&self) -> Option<&str>

Returns the service error kind when the error came from the service layer, otherwise None.

pub fn is_validation(&self) -> bool

Returns true when this error represents a validation failure.

Trait Implementations

impl Clone for ApplicationError

fn clone(&self) -> ApplicationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApplicationError

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

Formats the value using the given formatter.

impl Display for ApplicationError

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

Formats the value using the given formatter.

impl Error for ApplicationError

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<PortError> for ApplicationError

fn from(error: PortError) -> Self

Converts to this type from the input type.

impl From<ProviderError> for ApplicationError

fn from(error: ProviderError) -> Self

Converts to this type from the input type.

impl PartialEq for ApplicationError

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

impl Serialize for ApplicationError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
