Methods

impl Instructions

fn from_program(program: Program) -> Result<Self, Error>

Generate instructions from the given program syntax tree

fn optimize(&mut self, level: OptimizationLevel)

Optimize the instructions based on the given optimization level

fn len(&self) -> usize

The number of instructions in this instructions set

fn move_relative(&mut self, from: usize, to: usize)

Add instructions that move from a given offset to the other offset using the fewest instructions possible

fn move_right(&mut self)

Add an instruction to move one cell to the right

fn move_right_by(&mut self, n: usize)

Add instructions that move n cells to the right

fn move_left(&mut self)

Add an instruction to move one cell to the left

fn move_left_by(&mut self, n: usize)

Add instructions that move n cells to the left

fn increment_relative(&mut self, from: u8, to: u8)

Adds instructions that increment/decrement the current cell from the given value to the other given value

fn increment(&mut self)

Add an instruction to increment the current cell once

fn increment_by(&mut self, n: u8)

Add instructions that increment the current cell n times

fn decrement(&mut self)

Add an instruction to decrement the current cell once

fn decrement_by(&mut self, n: u8)

Add instructions that decrement the current cell n times

fn zero(&mut self)

Adds instructions which set the cell at the current position to zero regardless of its current value

fn zero_cells(&mut self, n: usize)

Adds instructions which set the next n cells (including the current one) to zero Example: zero_cells(3) will set the current cell and the next two to zero

fn store_bytes(&mut self, bytes: &[u8])

Stores the given bytes in each location starting at the current cell The pointer ends up at the cell immediately after the last character written IMPORTANT: Assumes that the current cell and all consecutive cells to be written into are zero to begin with

fn write(&mut self)

Add an instruction that will write the current cell

fn write_consecutive(&mut self, n: usize)

Add instructions that will write the next n consecutive cells starting at the current cell

fn read(&mut self)

Add an instruction that will read a single byte into the current cell

fn read_consecutive(&mut self, n: usize)

Add instructions that will read input into the next n consecutive cells starting at the current cell

fn jump_forward_if_zero(&mut self)

Add an instruction which will only jump forward to the matching jump backward instruction if the current cell is zero

fn jump_backward_unless_zero(&mut self)

Add an instruction which will only jump backward to the previous matching jump forward instruction if the current cell is not zero

fn remove(&mut self, index: usize) -> Instruction

Trait Implementations

impl Debug for Instructions

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for Instructions

fn eq(&self, __arg_0: &Instructions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Instructions) -> bool

This method tests for !=.

impl Clone for Instructions

fn clone(&self) -> Instructions

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Into<String> for Instructions

fn into(self) -> String

impl IntoIterator for Instructions

type Item = Instruction

The type of the elements being iterated over.

type IntoIter = IntoIter<Self::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Index<usize> for Instructions

type Output = Instruction

fn index(&self, index: usize) -> &Self::Output

The method for the indexing (container[index]) operation
