Enum ProgramError 

pub enum ProgramError {
    NotYet(NotYet),
    Lift(String),
    Graph(GraphError),
    Lower(LowerError),
}

Why the engine has no program for a model: the author cannot write its step, the front end cannot lift it, or its step graph holds a block the engine has no unit for.

Variants

NotYet(NotYet)

Lift(String)

Graph(GraphError)

Lower(LowerError)

Trait Implementations

impl Clone for ProgramError

fn clone(&self) -> ProgramError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProgramError

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

Formats the value using the given formatter.

impl Display for ProgramError

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

Formats the value using the given formatter.

impl Error for ProgramError

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 From<ProgramError> for EngineError

fn from(e: ProgramError) -> Self

Converts to this type from the input type.

impl PartialEq for ProgramError

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