Struct Exposure

pub struct Exposure<AccountId, Balance>
where
    Balance: HasCompact,
{
    pub total: Balance,
    pub own: Balance,
    pub others: Vec<IndividualExposure<AccountId, Balance>>,
}

A snapshot of the stake backing a single validator in the system.

Fields

total: Balance

The total balance backing this validator.

own: Balance

The validator’s own stash that is exposed.

others: Vec<IndividualExposure<AccountId, Balance>>

The portions of nominators stashes that are exposed.

Implementations

impl<AccountId, Balance> Exposure<AccountId, Balance>

where AccountId: Clone, Balance: HasCompact + AtLeast32BitUnsigned + Copy + MaxEncodedLen,

pub fn split_others(&mut self, n_others: u32) -> Exposure<AccountId, Balance>

Splits self into two instances of exposures.

n_others individual exposures are consumed from self and returned as part of the new exposure.

Since this method splits others of a single exposure, total.own will be the same for both self and the returned exposure.

pub fn into_pages( self, page_size: u32, ) -> (PagedExposureMetadata<Balance>, Vec<ExposurePage<AccountId, Balance>>)

Converts an Exposure into PagedExposureMetadata and multiple chunks of IndividualExposure with each chunk having maximum of page_size elements.
