Constant literals in a function

ConstantValues are stored in a Procedure’s constant table. Instructions from that procedure can refer to its constant values with a ConstantKey (from bytecode::operand). A constant key is just an index into that table.

Each procedure has its own table of ConstantValues.

A VirtualMachine can create a runtime Value directly from a ConstantValue.

impl PartialEq<ConstantValue> for ConstantValue

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<ConstantValue> for ConstantValue

fn partial_cmp(&self, other: &ConstantValue) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
