Struct MachiError 

pub struct MachiError { /* private fields */ }

Kernel error with stable code, message, and optional source.

Implementations

impl MachiError

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

Create an error with code and message.

Retry class defaults to ErrorCode::default_retry.

pub const fn with_retry(self, retry: RetryClass) -> Self

Attach retry classification (overrides default).

pub fn with_source(self, source: impl Error + Send + Sync + 'static) -> Self

Attach a source error.

pub const fn code(&self) -> ErrorCode

Stable code.

pub const fn retry_class(&self) -> RetryClass

Retry class.

pub fn message(&self) -> &str

Human-readable message.

pub fn cancelled(message: impl Into<String>) -> Self

Convenience: cancelled-style runtime error.

Trait Implementations

impl Clone for MachiError

fn clone(&self) -> MachiError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MachiError

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

Formats the value using the given formatter.

impl Display for MachiError

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

Formats the value using the given formatter.

impl Error for MachiError

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
