Struct cwe_checker_lib::intermediate_representation::ExternSymbol

pub struct ExternSymbol {
    pub tid: Tid,
    pub addresses: Vec<String>,
    pub name: String,
    pub calling_convention: Option<String>,

An extern symbol represents a funtion that is dynamically linked from another binary.

Fields

tid: Tid

The term ID of the extern symbol.

addresses: Vec<String>

Addresses of possibly multiple locations of the same extern symbol

name: String

The name of the extern symbol

calling_convention: Option<String>

The calling convention used for the extern symbol if known

parameters: Vec<Arg>

Parameters of an extern symbol. May be empty if there are no parameters or the parameters are unknown.

return_values: Vec<Arg>

Return values of an extern symbol. May be empty if there is no return value or the return values are unknown.

no_return: bool

If set to true, the function is assumed to never return to its caller when called.

has_var_args: bool

If the function has a variable number of parameters, this flag is set to true.

Implementations

impl ExternSymbol

pub fn get_unique_return_register(&self) -> Result<&Variable, Error>

If the extern symbol has exactly one return value that is passed in a register, return the register.

pub fn get_unique_parameter(&self) -> Result<&Arg, Error>

If the extern symbol has exactly one parameter, return the parameter.

pub fn get_calling_convention<'a>( &self, project: &'a Project ) -> &'a CallingConvention

Get the calling convention corresponding to the extern symbol.

Trait Implementations

impl Clone for ExternSymbol

fn clone(&self) -> ExternSymbol

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExternSymbol

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExternSymbol

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ExternSymbol

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

Formats the value using the given formatter.

impl Hash for ExternSymbol

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 ExternSymbol

fn eq(&self, other: &ExternSymbol) -> 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 ExternSymbol

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 ExternSymbol
