Struct sp_npos_elections::Assignment
source · pub struct Assignment<AccountId, P: PerThing> {
pub who: AccountId,
pub distribution: Vec<(AccountId, P)>,
}
Expand description
A voter’s stake assignment among a set of targets, represented as ratios.
Fields§
§who: AccountId
Voter’s identifier.
distribution: Vec<(AccountId, P)>
The distribution of the voter’s stake.
Implementations§
source§impl<AccountId: IdentifierT, P: PerThing128> Assignment<AccountId, P>
impl<AccountId: IdentifierT, P: PerThing128> Assignment<AccountId, P>
sourcepub fn into_staked(self, stake: ExtendedBalance) -> StakedAssignment<AccountId>
pub fn into_staked(self, stake: ExtendedBalance) -> StakedAssignment<AccountId>
Convert from a ratio assignment into one with absolute values aka. StakedAssignment
.
It needs stake
which is the total budget of the voter.
Note that this might create un-normalized assignments, due to accuracy loss of P
. Call
site might compensate by calling try_normalize()
on the returned StakedAssignment
as a
post-precessing.
If an edge ratio is Bounded::min_value()
, it is dropped. This edge can never mean
anything useful.
sourcepub fn try_normalize(&mut self) -> Result<(), &'static str>
pub fn try_normalize(&mut self) -> Result<(), &'static str>
Try and normalize this assignment.
If Ok(())
is returned, then the assignment MUST have been successfully normalized to 100%.
§Errors
This will return only if the internal normalize
fails. This can happen if sum of
self.distribution.map(|p| p.deconstruct())
fails to fit inside UpperOf<P>
. A user of
this crate may statically assert that this can never happen and safely expect
this to
return Ok
.
