You could simplify some code.

bf/src/main.rs

Line 32 in 698173c

fn lex(source: String) -> Vec<OpCode> {

The code at the above link can be simplified.

fn lex(source: String) -> Vec<OpCode> {
    let mut operations = Vec::new();
    for symbol in source.chars() {
        match symbol {
            '>' => operations.push(OpCode::IncrementPointer),
            '<' => operations.push(OpCode::DecrementPointer),
            '+' => operations.push(OpCode::Increment),
            '-' => operations.push(OpCode::Decrement),
            '.' => operations.push(OpCode::Write),
            ',' => operations.push(OpCode::Read),
            '[' => operations.push(OpCode::LoopBegin),
            ']' => operations.push(OpCode::LoopEnd),
            _ => ()
        };
    }
    operations
}

You used the same pattern elsewhere as well.
