Struct air_interpreter_data::FoldSubTraceLore

pub struct FoldSubTraceLore {
    pub value_pos: TracePos,
    pub subtraces_desc: Vec<SubTraceDesc>,
}
Expand description

Let’s consider an example of trace that could be produces by the following fold: (fold $stream v (call 1) (call 2) (next v) (call 3) (call 4) ) x Having started with stream with two elements {v1, v2} the resulted trace would looks like [(1) (2)] [(1) (2)] [(3) (4)] [(3) (4)] <— the sequence of call states v1 v2 v2 v1 <–– corresponding values from $stream that the iterable v had at the moment of call

From this example, it could be seen that each instruction sequence inside fold is divided into two intervals (left and right), each of these intervals has borders [begin, end). So, this struct describes position inside overall execution_step trace belongs to one fold iteration.

Fields§

§value_pos: TracePos

Position of current value in a trace.

§subtraces_desc: Vec<SubTraceDesc>

Descriptors of a subtrace that are corresponded to the current value. Technically, now it always contains two values, and Vec here is used to have a possibility to handle more than one next inside fold in future.
