Struct lief::dwarf::variable::Variable

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

This class represents a DWARF variable which can be owned by a crate::dwarf::Function or a crate::dwarf::CompilationUnit

Implementations

impl Variable<'_>

pub fn name(&self) -> String

Name of the variable (usually demangled)

pub fn linkage_name(&self) -> Option<String>

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

This name differs from Variable::name as it is usually mangled.

pub fn address(&self) -> Result<i64, Error>

Address of the variable.

If the variable is static, it returns the virtual address where it is defined. If the variable is stack-based, it returns the relative offset from the frame based register.

If the address can’t be resolved, it returns an Error.

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

Return the size of the variable (or an Error if it can’t be resolved).

This size is defined by its type.

pub fn is_constexpr(&self) -> bool

Whether it’s a constexpr variable

pub fn is_stack_based(&self) -> bool

Whether this variable is allocated on the stack

pub fn debug_location(&self) -> DebugLocation

The original source location where the variable is defined.

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

Return the type of this variable

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

The scope in which this variable is defined

pub fn description(&self) -> String

Description (DW_AT_description) of the variable or an empty string
