Enum ExpansionError 

pub enum ExpansionError {
    DivisionByZero,
    NegativeRoot(u32),
    Coefficient(String),
}

Why a coefficient or an operation of an expansion is not given.

Variants

DivisionByZero

The reciprocal of zero.

NegativeRoot(u32)

An even root of a negative value.

Coefficient(String)

A coefficient’s own refusal, in its own words.

Trait Implementations

impl Clone for ExpansionError

fn clone(&self) -> ExpansionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpansionError

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

Formats the value using the given formatter.

impl Display for ExpansionError

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

Formats the value using the given formatter.

impl PartialEq for ExpansionError

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