Struct DebugInfo 

pub(crate) struct DebugInfo {
    elf_data: Option<DebugInfoSource>,
    context: Mutex<Option<Option<Context<EndianArcSlice<RunTimeEndian>>>>>,
}

Fields

elf_data: Option<DebugInfoSource>

The ELF image, kept around (or reopened) so the DWARF sections can be loaded on first use. None for non-ELF artifacts.

context: Mutex<Option<Option<Context<EndianArcSlice<RunTimeEndian>>>>>

None until first accessed; Some(None) once loading was attempted and failed (or there was no ELF image to load from).

addr2line::Context caches parsed DWARF units behind plain OnceCells internally, so it is Send but not Sync — a Mutex serializes lookups from concurrent backtraces/traps instead of exposing a &Context that could be read from multiple threads at once.

Implementations

impl DebugInfo

pub(crate) fn new(elf_data: Option<DebugInfoSource>) -> Self

pub(crate) fn with_context<T>( &self, f: impl FnOnce(Option<&Context<EndianArcSlice<RunTimeEndian>>>) -> T, ) -> T

Runs f with the DWARF context, building it from the ELF image on first access. f receives None if there is no ELF image, or the image has no (or malformed) DWARF debug info.
