Function build_trace 

pub fn build_trace(witness: VmWitness) -> Result<VmTrace, ExecutionError>

Builds the main trace from the provided trace states in parallel.

Example

use miden_assembly::Assembler;
use miden_processor::{DefaultHost, FastProcessor, StackInputs};

let program = Assembler::default()
    .assemble_program("prg", "begin push.1 drop end")
    .unwrap()
    .unwrap_program();
let mut host = DefaultHost::default();

let execution_witness = FastProcessor::new(StackInputs::default())
    .execute_for_proving_sync(&program, &mut host)
    .unwrap();
let (vm_witness, _) = execution_witness.into_parts();
let trace = miden_processor::trace::build_trace(vm_witness).unwrap();

assert_eq!(*trace.program_hash(), program.hash());
