Enum cranelift_codegen::cursor::CursorPosition

pub enum CursorPosition {
    Nowhere,
    At(Inst),
    Before(Ebb),
    After(Ebb),
}

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(Ebb)

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

After(Ebb)

Cursor is pointing after the end of an EBB. New instructions will be appended to the EBB.
