Struct LogCheckpoint 

pub struct LogCheckpoint<'a> { /* private fields */ }

Borrowed complete checkpoint view; obtaining/iterating it allocates nothing. Hosts own encoding budgets. The immutable borrow keeps rows and watermarks fixed.

Implementations

impl<'a> LogCheckpoint<'a>

pub const fn limits(&self) -> Limits

Fixed retention limits.

pub fn entries( &self, ) -> impl ExactSizeIterator<Item = &'a Entry> + DoubleEndedIterator + 'a

pub const fn next_sequence(&self) -> Option<u64>

Next identity, including permanent exhaustion after complete pruning.

pub const fn last_created_at_secs(&self) -> Option<u64>

Last admitted time, including after complete pruning.
