Session overlay revision the snapshot was built from.

The memories, in presentation order.

§token_count: u16

Implementations§

Source§

impl PreparedMemorySnapshot

Source

pub fn empty(turn_id: TurnId) -> Self

An empty snapshot for a turn.

Source

pub fn is_empty(&self) -> bool

Whether the snapshot holds anything.

Source

pub fn is_fresh(&self, now: DateTime<Utc>) -> bool

Whether the snapshot is still fresh at now.

Source

pub fn satisfies(&self, query: &str, now: DateTime<Utc>) -> bool

Whether this snapshot answers the query the model actually asked with.

A prepared snapshot is speculative: it was built from the transcript, not from the tool arguments. When the model asks something the speculation did not anticipate, the caller falls back to a live search rather than answering the wrong question quickly.

Source

pub fn to_tool_payload(&self) -> Value

The tool payload handed back to the model (§39.2).
