Struct VmExecutor 

Source 
pub struct VmExecutor<F, VC>
where
    VC: VmExecutionConfig<F>,
{
    pub config: VC,
    /* private fields */
}
Expand description

VmExecutor is the struct that can execute an arbitrary program, provided in the form of a VmExe, for a fixed set of OpenVM instructions corresponding to a VmExecutionConfig. Internally once it is given a program, it will preprocess the program to rewrite it into a more optimized format for runtime execution. This instance of the executor will be a separate struct specialized to running a fixed program on different program inputs.
