Struct Dwarf 

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

DWARF debugging information parsed from an ELF image.

Dwarf encapsulates parsed DWARF sections and a mapping from compile unit offsets to address ranges. It provides helpers to build the DWARF representation from an executable and resolve addresses to source locations.

Implementations

impl<'a> Dwarf<'a>

pub fn build(process: &'a Info) -> Result<Self>

Builds a Dwarf struct from the given process information.

Arguments

• process - The process information.

Errors

Returns an Err upon any failure to retrieve ELF sections or parse DWARF format.

Returns

Returns a Dwarf struct on success, wrapped in an Ok variant. Returns an error on failure, wrapped in an Err variant.

pub fn addr2line(&self, addr: u64) -> Result<Option<LineInfo>>

Resolves the source file name and line number for a given address in the binary.

Arguments

• addr: The address in the binary’s address space.

Errors

Returns an error if there’s any failure in reading or parsing the DWARF debug information.

Returns

• Ok(Some(LineInfo)): The resolved source file name and line number.
• Ok(None): The address does not correspond to any source line information.
• Err: Error reading or parsing the DWARF information.
