SessionRecollection

Struct SessionRecollection 

Source
pub struct SessionRecollection { /* private fields */ }
Expand description

What earlier sessions in this scope decided, as one session reads it when it opens.

A rendering, not a copy of the memory. Two rules make it one:

Decisions and constraints first. A session opening has a bound on what it can carry, and what it carries first is what a later session is most likely to act on: what was settled, and what was ruled out. Observations and outcomes follow. Inside each group the order is the order the entries came back in, so a backend that keeps its writes in order stays readable as a sequence.

Bounded, and it says when the bound bit. The rendering stops at the first entry that will not fit and reports itself truncated. An entry too large for the whole budget is dropped rather than cut: half a decision is a sentence that says something else.

Implementations§

Source§

impl SessionRecollection

Source

pub fn rendered( scope: MemoryScope, recalled: &[MemoryEntry], budget: RecollectionBudget, ) -> Self

Render what a scope holds into what an opening can carry.

Source

pub fn scope(&self) -> &MemoryScope

Source

pub fn entries(&self) -> &[RecalledEntry]

Source

pub const fn completeness(&self) -> RecollectionCompleteness

Source

pub fn is_empty(&self) -> bool

Nothing came back. A session with nothing to recall records nothing, so its stream is the stream it would have had before memory could be read at all.
