Struct sp_staking::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.

where Balance: HasCompact + HasCompact + MaxEncodedLen,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<Balance> MaxEncodedLen for PagedExposureMetadata<Balance>

where Balance: HasCompact + HasCompact + MaxEncodedLen,

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl<Balance: Ord + HasCompact + MaxEncodedLen> Ord for PagedExposureMetadata<Balance>

fn cmp(&self, other: &PagedExposureMetadata<Balance>) -> Ordering
