Enum Error

pub enum Error {
    SolutionWeightOverflow,
    SolutionTargetOverflow,
    SolutionInvalidIndex,
    SolutionInvalidPageIndex,
    ArithmeticError,
    InvalidSupportEdge,
    TooManyVoters,
    BoundsExceeded,
}

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

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.

BoundsExceeded

Some bounds were exceeded when converting election types.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Decode for Error

fn decode<__CodecInputEdqy>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Error, Error>

where __CodecInputEdqy: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for Error

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

where __CodecOutputEdqy: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

impl TypeInfo for Error

type Identity = Error

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl DecodeWithMemTracking for Error

impl EncodeLike for Error

impl Eq for Error

impl StructuralPartialEq for Error
