Struct Variable

pub struct Variable<R: Reader<Offset = usize>> {
    pub name: Option<String>,
    pub value: EvaluatorValue<R>,
    pub source: Option<SourceInformation>,
}

Defines what debug information a variable has.

Fields

name: Option<String>

The name of the variable.

value: EvaluatorValue<R>

A tree structured like the variable type in DWARF, but it also contains the values

source: Option<SourceInformation>

The source code location where the variable was declared.

Implementations

impl<R: Reader<Offset = usize>> Variable<R>

pub fn get_variable<M: MemoryAccess>( dwarf: &Dwarf<R>, registers: &Registers, memory: &mut M, dwarf_offset: DwarfOffset, frame_base: Option<u64>, cwd: &str, ) -> Result<Variable<R>>

Retrieve the variables debug information.

Description:

• dwarf - A reference to gimli-rs Dwarf struct.
• registers - A reference to the Registers struct.
• memory - A reference to a struct that implements the MemoryAccess trait.
• section_offset - A offset to the compilation unit where the DIE for the variable is located.
• unit_offset - A offset into the compilation unit where the DIE representing the variable is located.
• frame_base - The value of the frame base, which is often needed to evaluate the variable.
• cwd - The work directory of the program being debugged.

This function will go through the DIE in the compilation unit to find the necessary debug information. Then it will use that information to evaluate the value of the variable.

Trait Implementations
