Enum ConvertError 

pub enum ConvertError {
    ExpOperator(String),
    UnsupportedOperator(String),
    UnsupportedFunction(String),
    RootNode(String),
    ConstOperator(String),
    VariableNotFound(String),
}

Errors that can occur during conversion from evalexpr AST to our internal AST representation.

This enum represents various failure modes when converting the evalexpr expression tree into our own AST format that can be used for JIT compilation and symbolic differentiation.

Variants

ExpOperator(String)

Error when trying to convert an exponent that is not a valid integer constant

UnsupportedOperator(String)

Error when encountering an operator that is not supported by our implementation

UnsupportedFunction(String)

Error when encountering a function that is not supported by our implementation

RootNode(String)

Error when the root node does not have exactly one child

ConstOperator(String)

Error when a constant value is not a floating point number

VariableNotFound(String)

Error when a variable is not found in the variable map

Trait Implementations

impl Debug for ConvertError

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

Formats the value using the given formatter.

impl Display for ConvertError

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

Formats the value using the given formatter.

impl Error for ConvertError

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<ConvertError> for EquationError

fn from(source: ConvertError) -> Self

Converts to this type from the input type.
