Struct UseSite 

pub struct UseSite {
    pub block: usize,
    pub instruction: usize,
    pub is_phi_operand: bool,
}

Use site of an SSA variable.

Records where in the program a variable is used (read).

Fields

block: usize

The block where this variable is used.

instruction: usize

The instruction index within the block.

For phi node operands, this refers to the phi node’s index in the block’s phi node list (not the instruction list).

is_phi_operand: bool

Whether this use is in a phi node operand.

Implementations

impl UseSite

pub const fn instruction(block: usize, instr_idx: usize) -> Self

Creates a use site for a regular instruction.

pub const fn phi_operand(block: usize, phi_idx: usize) -> Self

Creates a use site for a phi node operand.

Trait Implementations

impl Clone for UseSite

fn clone(&self) -> UseSite

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UseSite

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

Formats the value using the given formatter.

impl PartialEq for UseSite

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