Struct KeyPage 

pub struct KeyPage { /* private fields */ }

One bounded page, validated against the request that produced it. Records and revision describe the same committed source read. next_after exists only when lookahead found another active record; an exactly full final page is terminal. Revisions advance on every mutation that can change the feed.

Implementations

impl KeyPage

pub fn try_new( revision: u64, as_of: Timestamp, after: Option<KeyId>, limit: NonZeroUsize, keys: Vec<CredentialRecord>, next_after: Option<KeyId>, ) -> Result<Self, StoreError>

Validate one page against the request (after, limit) that produced it. as_of is the instant the source selected active records at.

Errors

A StoreError when limit exceeds MAX_KEY_PAGE_LIMIT; revision exceeds MAX_KEY_REVISION; there are more than limit records; key ids do not strictly increase from after; a record’s not_after is at or before as_of; next_after is present on a page that is not full or does not name its last record; or the records fail CredentialSet::try_new.

pub fn validate_request( &self, after: Option<KeyId>, limit: NonZeroUsize, ) -> Result<(), StoreError>

Check that this page answers the request (after, limit).

Errors

A StoreError when either differs from the request the page was built for.

pub fn revision(&self) -> u64

The source revision the records were read at.

pub fn as_of(&self) -> Timestamp

The instant the source selected active records at.

pub fn records(&self) -> &[CredentialRecord]

The page’s records, in strictly increasing key-id order.

pub fn next_after(&self) -> Option<KeyId>

The cursor for the next page, which is this page’s last key id, or None when the page is terminal.

pub fn into_records(self) -> Vec<CredentialRecord>

Consume the page, returning its records.
