Struct SaddleError 

pub struct SaddleError { /* private fields */ }

An error safe to propagate across Saddle component boundaries.

message must not contain credentials, SQL parameters, request payloads or other sensitive implementation details.

Implementations

impl SaddleError

pub fn new( kind: ErrorKind, code: &'static str, message: impl Into<String>, ) -> Self

pub const fn kind(&self) -> ErrorKind

pub const fn code(&self) -> &'static str

pub fn message(&self) -> &str

pub fn with_diagnostic(self, diagnostic: Diagnostic) -> Self

pub fn diagnostic(&self) -> Option<&Diagnostic>

pub fn during_cleanup_of(self, primary: &Self) -> Self

Preserve this cleanup occurrence and link it to the independent primary.

pub fn wrap_diagnostic(self, cause: DiagnosticCause) -> Self

Propagate existing diagnosis without changing its origin or error semantics. An uninstrumented upstream error remains uninstrumented, never fabricated.

Trait Implementations

impl Debug for SaddleError

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

Formats the value using the given formatter.

impl Display for SaddleError

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

Formats the value using the given formatter.

impl Error for SaddleError

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.
