Struct lief::dwarf::function::Function

pub struct Function<'a> { /* private fields */ }

This structure represents a DWARF function which can be associated with either: DW_TAG_subprogram or DW_TAG_inlined_subroutine.

Implementations

impl Function<'_>

pub fn name(&self) -> String

The name of the function (DW_AT_name)

pub fn linkage_name(&self) -> String

The name of the function which is used for linking (DW_AT_linkage_name).

This name differs from Function::name as it is usually mangled. The function return an empty string if the linkage name is not available.

pub fn address(&self) -> Result<u64, Error>

Return the address of the function (DW_AT_entry_pc or DW_AT_low_pc).

pub fn variables(&self) -> Variables<'_>

Return an iterator of variables (DW_TAG_variable) defined within the scope of this function. This includes regular stack-based variables as well as static ones.

pub fn is_artificial(&self) -> bool

Whether this function is created by the compiler and not present in the original source code

pub fn is_external(&self) -> bool

Whether the function is defined outside the compilation unit (DW_AT_external)

pub fn size(&self) -> u64

Return the size taken by this function in the binary

pub fn ranges(&self) -> Vec<Range>

Ranges of virtual addresses owned by this function

pub fn debug_location(&self) -> DebugLocation

Original source code location

pub fn return_type(&self) -> Option<Type<'_>>

Return the Type associated with the return type of this function.

pub fn parameters(&self) -> ParametersIt<'_>

Return an iterator over the Parameters of this function

pub fn thrown_types(&self) -> ThrownTypes<'_>

List of exceptions (types) that can be thrown by the function.

For instance, given this Swift code:

func summarize(_ ratings: [Int]) throws(StatisticsError) {
  // ...
}

Function::thrown_types returns one element associated with the Type: StatisticsError.

pub fn scope(&self) -> Option<Scope<'_>>

The scope in which this function is defined

pub fn instructions(&self) -> Instructions<'_>

Disassemble the current function by returning an iterator over the assembly::Instructions
