Enum InterpreterError 

pub enum InterpreterError {
    MultipleRead(NodeId),
    MultipleWrite(NodeId),
    SSAError(SSAError),
    TypeError(EdgeId),
    ArityError(EdgeId),
    Load(EdgeId, Path),
    ApplyError(EdgeId),
}

Evaluation errors

Variants

MultipleRead(NodeId)

A node appeared as a source of multiple hyperedges, and so interpreting tried to read a value that had already been consumed.

MultipleWrite(NodeId)

A node appeared as a target of multiple hyperedges, and so was written to multiple times during interpretation.

SSAError(SSAError)

A term could not be mapped into SSA form

TypeError(EdgeId)

Could not apply an operation because arguments were not of the correct form.

ArityError(EdgeId)

Unexpected number of arguments to an operation

Load(EdgeId, Path)

Interpreter failed to handle a Load operation

ApplyError(EdgeId)

Interpreter-specific error while trying to apply an op

Trait Implementations

impl Clone for InterpreterError

fn clone(&self) -> InterpreterError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InterpreterError

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

Formats the value using the given formatter.

impl Display for InterpreterError

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

Formats the value using the given formatter.

impl Error for InterpreterError

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<SSAError> for InterpreterError

fn from(value: SSAError) -> Self

Converts to this type from the input type.
