Enum FactsError 

pub enum FactsError {
    NoWorkflowImport,
    NoDefineCall,
    EntryFunctionNotIdentifiable,
}

Errors raised while reading workflow facts from source.

Variants

NoWorkflowImport

The entry-module source never imports aion/workflow, so it composes none of the recognised primitives and is not a workflow the scaffold generator understands.

NoDefineCall

No workflow.define(...) call was found, so the typed entry function the harness must drive cannot be identified.

EntryFunctionNotIdentifiable

A workflow.define(...) call was found but its last argument is not a bare function reference, so the typed entry function cannot be named.

Trait Implementations

impl Debug for FactsError

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

Formats the value using the given formatter.

impl Display for FactsError

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

Formats the value using the given formatter.

impl Eq for FactsError

impl Error for FactsError

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 FactsError

fn eq(&self, other: &FactsError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
