Enum cranelift_codegen::cursor::CursorPosition

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

The possible positions of a cursor.

Variants

Nowhere

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

At(Inst)

Tuple Fields

0: Inst

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

Before(Block)

Tuple Fields

0: 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)

Tuple Fields

0: Block

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