Enum FunctionError

pub enum FunctionError {
    WrongNumberOfEntries {
        expected_number_of_entries: usize,
        actual_number_of_entries: usize,
    },
}

Custom error that can occur with the Function class defined below.

Variants

WrongNumberOfEntries

The Function could not compute the function value because the Vector provided does not have the right number of arguments.

Fields

expected_number_of_entries: usize

Expected number of arguments.

actual_number_of_entries: usize

Actual number of arguments.

Trait Implementations

impl Debug for FunctionError

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

Formats the value using the given formatter.

impl Display for FunctionError

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

Formats the value using the given formatter.

impl PartialEq for FunctionError

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