Enum RunGraphError 

pub enum RunGraphError {}

Top-level error raised by run_graph.

This revision defines no variants: a single task’s failure does not abort the run (per EXEC-010), and every failure path the scheduler can currently produce is surfaced as a per-task RunTaskError captured in RunGraphOutcome::task_errors or as a typed RuntimeInvariantViolation in RunGraphOutcome::invariant_violations. The enum exists so a future scheduler-level diagnostic (e.g. a mutex acquisition error not attributable to a single task) can grow without changing run_graph’s signature.

Trait Implementations

impl Debug for RunGraphError

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

Formats the value using the given formatter.

impl Display for RunGraphError

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

Formats the value using the given formatter.

impl Error for RunGraphError

where Self: Debug + Display,

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 ErrorCompat for RunGraphError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
