pub enum CursorPosition {
    Nowhere,
    At(Inst),
    Before(Block),
    After(Block),
}
Expand description

The possible positions of a cursor.

Variants§

§

Nowhere

Cursor is not pointing anywhere. No instructions can be inserted.

§

At(Inst)

Cursor is pointing at an existing instruction. New instructions will be inserted before the current instruction.

§

Before(Block)

Cursor is before the beginning of a block. No instructions can be inserted. Calling next_inst() will move to the first instruction in the block.

§

After(Block)

Cursor is pointing after the end of a block. New instructions will be appended to the block.
