pub enum CursorPosition {
    Nowhere,

}

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.
