Variants

Output

Output Writes output buffer to stdout

Input

Input Reads one byte from stdin to the current cell

Loop(Vec<Token>)

Loop(content) Runs content in loop while current cell is not zero

Move(i32)

Move(offset) Moves data pointer by offset cells

Add(i32, i32)

Add(offset, value) Adds value to cell at offset

Set(i32, i32)

Set(offset, value) Sets cell at offset to value

MulCopy(i32, i32, i32)

MulCopy(src, dest, mul) Adds product of mul and the value at offset src to the cell at offset dest

Scan(i32)

Scan(offset) Equivalent to Loop(Move(offset))

LoadOut(i32, i32)

LoadOut(offset, add) Appends the value of the cell at offset plus add to the output buffer

LoadOutSet(i32)

LoadOutSet(value) Appends the constant value value to the output buffer

If(i32, Vec<Token>)

LoadOutSet(offset, content) Runs content if the cell at offset is not zero

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a copy of the value.

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