Essential for parsing.
let mut buffer = PeekBuffer::from("Hello, World!");
// peek without consuming
while let Some(&c) = buffer.peek() {
println!("{}", c);
// advance to the next item (char in this situation)
buffer.advance_char();
// generally you should use buffer.advance() to move to the next element
// but if you're parsing a string, you should use buffer.advance_char()
// since it keeps track of the line and the column the cursor is at.
}
// peek with consuming
buffer.rewind_to_beginning();
while let Some(&c) = buffer.eat() {
println!("{}", c);
buffer.advance_char();
}
println!("{}", buffer.len());
