Variants

Adopted

Fields

rows: usize

appended: usize

first_key: usize

NoCarry

PrefixMismatch

Fields

common: usize

entry_rows: usize

ForeignHiddens

2026-09-25: No append plan because another non-zero ticket owns the stored hidden rows; otherwise the same refusal as NoHiddens.

Fields

owner: u64

2026-09-25: The ticket that owns the rows.

expected: u64

2026-09-25: The ticket that wanted to read them.

ForeignSession

2026-09-25: The slot held another session’s rows, or this request has no session. PrefixMismatch is instead an entry of this session whose prefix did not match.

Fields

entry_session: u64

prompt_session: u64

NoHiddens

Trait Implementations

impl Debug for CarryOutcome

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

Formats the value using the given formatter.

impl Display for CarryOutcome

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

Formats the value using the given formatter.

impl PartialEq for CarryOutcome

fn eq(&self, other: &CarryOutcome) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
