Trait Implementations

impl Clone for EvalError

fn clone(&self) -> EvalError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EvalError

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

Formats the value using the given formatter.

impl From<ImmixError> for EvalError

fn from(value: ImmixError) -> Self

Converts to this type from the input type.

impl PartialEq for EvalError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
