Struct cwe_checker_lib::intermediate_representation::Variable

pub struct Variable {
    pub name: String,
    pub size: ByteSize,
    pub is_temp: bool,
}

A variable represents a register with a known size and name.

Variables can be temporary (or virtual). In this case they do not represent actual physical registers and are only used to store intermediate results necessary for representing more complex assembly instructions. Temporary variables are only valid until the end of the current assembly instruction. However, one assembly instruction may span more than one basic block in the intermediate representation (but never more than one function).

Fields

name: String

The name of the variable. Equals the register name if the variable is a physical register.

size: ByteSize

The size (in bytes) of the variable.

is_temp: bool

Set to false for physical registers and to true for temporary (virtual) variables.

Trait Implementations

impl Clone for Variable

fn clone(&self) -> Variable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Variable

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Variable

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Variable

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

Formats the value using the given formatter.

impl From<&RegisterProperties> for Variable

fn from(register_prop: &RegisterProperties) -> IrVariable

Create a variable representing the same register as the given register_prop.

impl From<Variable> for Variable

fn from(pcode_var: Variable) -> IrVariable

Translate a P-Code variable into a register variable of the internally used IR. Panic if the variable does not represent a register.

impl Hash for Variable

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Variable

fn cmp(&self, other: &Variable) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Variable

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

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

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

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

impl PartialOrd for Variable

fn partial_cmp(&self, other: &Variable) -> 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.

impl Serialize for Variable

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Variable

impl StructuralEq for Variable

impl StructuralPartialEq for Variable
