folly::logging::appendRawObjectInfo

Append raw information about an object to a string.

Synopsis

Declared in <folly/logging/ObjectToString.h>

template<typename Arg>
void
appendRawObjectInfo(
    std::string& str,
    Arg const* arg);

Description

This is used as a fallback for objects that we do not otherwise know how to print. This emits:

  • The object type name (if RTTI is supported)

  • The object size

  • A hexdump of the object contents.

e.g. [MyStruct of size 4: 37 6f af 2a] [AnotherClass of size 8: f9 48 78 85 56 54 8f 54]

Parameters

NameDescription
strThe string to append the object information to.
argA pointer to the object to describe.
