Struct symbolic::debuginfo::macho::BcSymbolMap [−][src]
pub struct BcSymbolMap<'d> { /* fields omitted */ }
Expand description
An in-memory representation of the Apple bitcode symbol map.
This is an auxiliary file, not an object file. It can be used to provide de-obfuscated
symbol names to a MachObject
object using its
load_symbolmap
method.
It is common for bitcode builds to obfuscate the names in the object file’s symbol table
so that even the DWARF files do not have the actual symbol names. In this case the
build process will create a .bcsymbolmap
file which maps the obfuscated symbol names
back to the original ones. This structure can parse these files and allows providing
this information to the MachObject
so that it has the original symbol names instead
of __hidden#NNN_
ones.
See MachObject::load_symbolmap
for an
example of how to use this.
Implementations
Parses the BCSymbolMap.
A symbol map does not contain the UUID of its symbols, instead this is normally encoded in the filename.
Returns the name of a symbol if it exists in this mapping.
Examples
use symbolic_debuginfo::macho::BcSymbolMap;
// let data = std::fs::read("c8374b6d-6e96-34d8-ae38-efaa5fec424f.bcsymbolmap").unwrap();
let map = BcSymbolMap::parse(&data).unwrap();
assert_eq!(map.get(43), Some("Sources/Sentry/Public/SentryMessage.h"));
assert_eq!(map.get(usize::MAX), None); // We do not have this many entries
Resolves a name using this mapping.
If the name matches the __hidden#NNN_
pattern that indicates a BcSymbolMap
lookup it will be looked up the resolved name will be returned. Otherwise the name
is returned unchanged.
Examples
use symbolic_debuginfo::macho::BcSymbolMap;
// let data = std::fs::read("c8374b6d-6e96-34d8-ae38-efaa5fec424f.bcsymbolmap").unwrap();
let map = BcSymbolMap::parse(&data).unwrap();
assert_eq!(map.resolve("__hidden#43_"), "Sources/Sentry/Public/SentryMessage.h");
assert_eq!(map.resolve("_addJSONData"), "_addJSONData"); // #64
