Enum pallet_election_provider_multi_phase::FeasibilityError [−][src]
pub enum FeasibilityError { WrongWinnerCount, SnapshotUnavailable, NposElection(Error), InvalidVote, InvalidVoter, InvalidWinner, InvalidScore, InvalidRound, UntrustedScoreTooLow, }
Expand description
Errors that can happen in the feasibility check.
Variants
Wrong number of winners presented.
The snapshot is not available.
Kinda defensive: The pallet should technically never attempt to do a feasibility check when no snapshot is present.
NposElection(Error)
Internal error from the election crate.
A vote is invalid.
A voter is invalid.
A winner is invalid.
The given score was invalid.
The provided round is incorrect.
Comparison against MinimumUntrustedScore
failed.

pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
The counterpart to unchecked_from
.
Consume self to return an equivalent value of T
.
