Enum ProgramPoint

pub enum ProgramPoint {
    Inst(Inst),
    Block(Block),
}

A ProgramPoint represents a position in a function where the live range of an SSA value can begin or end. It can be either:

1. An instruction or
2. A block header.

This corresponds more or less to the lines in the textual form of Cranelift IR.

Variants

Inst(Inst)

An instruction in the function.

Block(Block)

A block header.

Implementations

impl ProgramPoint

pub fn unwrap_inst(self) -> Inst

Get the instruction we know is inside.

Trait Implementations

impl Clone for ProgramPoint

fn clone(&self) -> ProgramPoint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProgramPoint

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

Formats the value using the given formatter.

impl Display for ProgramPoint

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

Formats the value using the given formatter.

impl From<Block> for ProgramPoint

fn from(block: Block) -> Self

Converts to this type from the input type.

impl From<Inst> for ProgramPoint

fn from(inst: Inst) -> Self

Converts to this type from the input type.

impl PartialEq for ProgramPoint

fn eq(&self, other: &ProgramPoint) -> 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.
