Enum cwe_checker_lib::intermediate_representation::Arg

pub enum Arg {
    Register {
        expr: Expression,
        data_type: Option<Datatype>,
    },
    Stack {
        address: Expression,
        size: ByteSize,
        data_type: Option<Datatype>,
    },
}

A parameter or return argument of a function.

Variants

Register

Fields

expr: Expression

The expression evaluating to the argument.

data_type: Option<Datatype>

An optional data type indicator.

The argument is passed in a register

Stack

Fields

address: Expression

The expression that computes the address of the argument on the stack.

size: ByteSize

The size in bytes of the argument.

data_type: Option<Datatype>

An optional data type indicator.

The argument is passed on the stack.

Implementations

impl Arg

pub fn from_var(var: Variable, data_type_hint: Option<Datatype>) -> Arg

Generate a new register argument.

pub fn get_data_type(&self) -> Option<Datatype>

Returns the data type field of an Arg object.

pub fn eval_stack_offset(&self) -> Result<Bitvector, Error>

If the argument is a stack argument, return its offset relative to the current stack register value. Return an error for register arguments or if the offset could not be computed.

pub fn bytesize(&self) -> ByteSize

Return the bytesize of the argument.

Trait Implementations

impl Clone for Arg

fn clone(&self) -> Arg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Arg

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Arg

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Arg

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 PartialEq for Arg

fn eq(&self, other: &Arg) -> 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 Serialize for Arg

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
