Struct PagedExposureMetadata 

pub struct PagedExposureMetadata<Balance: HasCompact + MaxEncodedLen> {
    pub total: Balance,
    pub own: Balance,
    pub nominator_count: u32,
    pub page_count: Page,
}

Metadata for Paged Exposure of a validator such as total stake across pages and page count.

In combination with the associated ExposurePages, it can be used to reconstruct a full Exposure set of a validator. This is useful for cases where we want to query full set of Exposure as one page (for backward compatibility).

Fields

total: Balance

The total balance backing this validator.

own: Balance

The validator’s own stash that is exposed.

nominator_count: u32

Number of nominators backing this validator.

page_count: Page

Number of pages of nominators.

Implementations

impl<Balance> PagedExposureMetadata<Balance>

where Balance: HasCompact + MaxEncodedLen + Add<Output = Balance> + Sub<Output = Balance> + Saturating + PartialEq + Copy + Debug,

pub fn update_with<Max: Get<u32>>( self, others_balance: Balance, others_num: u32, ) -> Self

Consumes self and returns the result of the metadata updated with other_balances and of adding other_num nominators to the metadata.

Max is a getter of the maximum number of nominators per page.
