Struct cpr_bf::VMBuilder

pub struct VMBuilder<T: BrainfuckCell = u8, A: BrainfuckAllocator = DynamicAllocator, R: Read = Stdin, W: Write = Stdout> { /* private fields */ }

A builder struct for the default implementation of BrainfuckVM Create the default configuration with VMBuilder::new() or VMBuilder::default(), customize with the member functions, and build the final VM with VMBuilder::build()
