Lifecycle(LifecycleError)

Runtime failed while observing lifecycle transitions.

Metadata(MetadataError)

Implementations

impl PureflowError

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

Create an execution error.

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

Create a cancellation error.

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

Create a lifecycle observation error.

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

Create a metadata collection error.

pub const fn code(&self) -> ErrorCode

Stable error code for this failure.

pub const fn visibility(&self) -> ErrorVisibility

Whether this error should be shown directly to a human.

pub const fn retry_disposition(&self) -> RetryDisposition

Retry guidance for this failure.

Trait Implementations

impl Clone for PureflowError

fn clone(&self) -> PureflowError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PureflowError

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

Formats the value using the given formatter.

impl Display for PureflowError

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

Formats the value using the given formatter.

impl Error for PureflowError

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 PartialEq for PureflowError

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