Struct brainfoamkit_lib::VirtualMachineBuilder

pub struct VirtualMachineBuilder { /* private fields */ }

VirtualMachineBuilder is a builder for the VirtualMachine struct.

This builder allows you to set the program and tape_size for a VirtualMachine before building it. Both program and tape_size are optional. If they’re not provided, the VirtualMachine will be initialized with default values.

Examples

use brainfoamkit_lib::{
    Program,
    VirtualMachineBuilder,
};
let program = Program::default();
let vm = VirtualMachineBuilder::default()
    .program(program)
    .tape_size(1024)
    .build();

Implementations

impl VirtualMachineBuilder

pub const fn new() -> Self

Creates a new VirtualMachineBuilder with default values.

This function returns a new VirtualMachineBuilder with program and tape_size set to None. These values can be set later using the builder’s methods.

Returns

A new VirtualMachineBuilder with default values.

Examples

use brainfoamkit_lib::VirtualMachineBuilder;

let builder = VirtualMachineBuilder::new();

pub fn program(self, program: Program) -> Self

Set the program to be run by the virtual machine.

Arguments

• program - The program to be run by the virtual machine.

Returns

• Builder by value with the program set.

Examples

use brainfoamkit_lib::{
    Program,
    VirtualMachineBuilder,
};

let program = Program::from_string("++++++[>++++++++++<-]>+++++.");
let vm = VirtualMachineBuilder::new().program(program).build();

assert_eq!(
    vm.program(),
    Program::from_string("++++++[>++++++++++<-]>+++++.")
);

pub const fn tape_size(self, tape_size: usize) -> Self

Set the size of the tape to be used by the virtual machine. The default size is 30,000.

Arguments

• tape_size - The size of the tape to be used by the virtual machine.

Returns

• Builder by value with the tape size set.

Examples

use brainfoamkit_lib::VirtualMachineBuilder;

let vm = VirtualMachineBuilder::new().tape_size(100).build();

assert_eq!(vm.length(), 100);

pub fn build(self) -> VirtualMachine

Build the virtual machine.

Returns

• The virtual machine.

Examples

use brainfoamkit_lib::{
    Program,
    VirtualMachineBuilder,
};

let program = Program::from_string("++++++[>++++++++++<-]>+++++.");
let vm = VirtualMachineBuilder::new()
    .program(program)
    .tape_size(100)
    .build();
