Struct JournalState 

pub struct JournalState {

    pub messages: Vec<ChatMessage>,
    pub unpersisted: Vec<ChatMessage>,
    pub checkpoint_messages: Option<usize>,
    pub undo_stack: Vec<Vec<ChatMessage>>,
    pub steer_queue: Vec<String>,
    pub follow_up_queue: Vec<String>,
    pub plan: Vec<PlanEntry>,
    pub renames: Vec<(String, String)>,
    pub upgrades: Vec<(u32, u32, String)>,
    pub model_changes: Vec<ModelChangeRecord>,
    pub usage: Vec<UsageRecord>,
    pub records: usize,
    pub skipped: usize,
}

The state a journal describes once folded up.

Fields

messages: Vec<ChatMessage>

The live conversation, after every recorded rewind/unrewind.

unpersisted: Vec<ChatMessage>

Messages recorded AFTER the last JournalOp::Checkpoint — the turn (or part of a turn) that a crash would have lost, because the end-of-turn transcript rewrite never ran. Empty in the ordinary case, where the last thing that happened was a clean persist.

checkpoint_messages: Option<usize>

Messages the last JournalOp::Checkpoint said the transcript holds — None when the journal has no checkpoint yet.

undo_stack: Vec<Vec<ChatMessage>>

Tails removed by rewinds that have not been undone, newest last — the proof that a rewind loses nothing.

steer_queue: Vec<String>

Still-pending mid-turn steering inputs, oldest first.

follow_up_queue: Vec<String>

Still-pending at-idle follow-up inputs, oldest first.

plan: Vec<PlanEntry>

The current plan (empty when the session never recorded one).

renames: Vec<(String, String)>

Every rename this session’s handle has been through, in order.

upgrades: Vec<(u32, u32, String)>

Every in-place format upgrade recorded for this session.

model_changes: Vec<ModelChangeRecord>

BP-13: every mid-session model change recorded, in order.

usage: Vec<UsageRecord>

BP-13: every per-turn usage record written, in order.

records: usize

Well-formed records read.

skipped: usize

Lines skipped as unreadable — a torn trailing record after a crash, or a foreign line someone concatenated in.

Implementations

impl JournalState

pub fn queue(&self, kind: QueueKind) -> &[String]

Pending inputs for one queue.

pub fn plan_pairs(&self) -> Vec<(String, String)>

The plan as (step, status) pairs — the shape crate::tools::UpdatePlanTool hands out.

Trait Implementations

impl Clone for JournalState

fn clone(&self) -> JournalState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JournalState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for JournalState

fn default() -> JournalState

Returns the “default value” for a type.
