Enum 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)

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.

Trait Implementations

impl Clone for CursorPosition

fn clone(&self) -> CursorPosition

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CursorPosition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CursorPosition

fn eq(&self, other: &CursorPosition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
