The errors that might occur in this crate and frame-election-provider-solution-type.

Variants

SolutionWeightOverflow

While going from solution indices to ratio, the weight of all the edges has gone above the total.

SolutionTargetOverflow

The solution type has a voter who’s number of targets is out of bound.

SolutionInvalidIndex

One of the index functions returned none.

SolutionInvalidPageIndex

One of the page indices was invalid.

ArithmeticError(&'static str)

An error occurred in some arithmetic operation.

InvalidSupportEdge

The data provided to create support map was invalid.

TooManyVoters

The number of voters is bigger than the MaxVoters bound.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl PartialEq for Error

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

impl Eq for Error

impl StructuralPartialEq for Error
