Struct tp_npos_elections::StakedAssignment [−][src]
A voter’s stake assignment among a set of targets, represented as absolute values in the scale
of ExtendedBalance
.
Fields
who: AccountId
Voter’s identifier
distribution: Vec<(AccountId, ExtendedBalance)>
The distribution of the voter’s stake.
Implementations
impl<AccountId> StakedAssignment<AccountId>
[src]
pub fn into_assignment<P: PerThing>(self) -> Assignment<AccountId, P> where
AccountId: IdentifierT,
[src]
AccountId: IdentifierT,
Converts self into the normal Assignment
type.
NOTE: This will always round down, and thus the results might be less than a full 100% P
.
Use a normalization post-processing to fix this. The data type returned here will
potentially get used to create a compact type; a compact type requires sum of ratios to be
less than 100% upon un-compacting.
If an edge stake is so small that it cannot be represented in T
, it is ignored. This edge
can never be re-created and does not mean anything useful anymore.
pub fn try_normalize(
&mut self,
stake: ExtendedBalance
) -> Result<(), &'static str>
[src]
&mut self,
stake: ExtendedBalance
) -> Result<(), &'static str>
Try and normalize this assignment.
If Ok(())
is returned, then the assignment MUST have been successfully normalized to
stake
.
NOTE: current implementation of .normalize
is almost safe to expect()
upon. The only
error case is when the input cannot fit in T
, or the sum of input cannot fit in T
.
Sadly, both of these are dependent upon the implementation of VoteLimit
, i.e. the limit of
edges per voter which is enforced from upstream. Hence, at this crate, we prefer returning a
result and a use the name prefix try_
.
pub fn total(&self) -> ExtendedBalance
[src]
Get the total stake of this assignment (aka voter budget).
