Enum ChainOutcome 

pub enum ChainOutcome {
    Return(i64),
    Deopt(i64),
}

What one chain run produced.

Variants

Return(i64)

The chain reached its Return; this is the returned value.

Deopt(i64)

A checked op side-exited; the payload is the RAW status-cell value. 1 is the plain marker (replay from the entry state — every effect confined to the private frame). (pc << 2) | 3 is a PRECISE exit: effects already landed, resume at bytecode pc.

Implementations

impl ChainOutcome

pub fn expect_return(self) -> i64

The returned value; panics on ChainOutcome::Deopt — for tests and callers of chains that contain no checked ops.

pub fn is_deopt(&self) -> bool

True when the run side-exited.

Trait Implementations

impl Clone for ChainOutcome

fn clone(&self) -> ChainOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainOutcome

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

Formats the value using the given formatter.

impl PartialEq for ChainOutcome

fn eq(&self, other: &ChainOutcome) -> 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.
