class DirectMemory
Defined at line 287 of file ../../src/lib/elfldltl/include/lib/elfldltl/memory.h
This does direct memory access to an ELF load image already mapped in.
Addresses in the ELF metadata are relative to a given base address that
corresponds to the beginning of the image this object points to.

void DirectMemory ()Defined at line 289 of file ../../src/lib/elfldltl/include/lib/elfldltl/memory.h
void DirectMemory (const DirectMemory & )The Memory API is always used by lvalue reference, so Memory objects don't
need to be either copyable or movable. But DirectMemory is really just a
pointer holder, so it can be easily copied.

void DirectMemory (std::span<std::byte> image, uintptr_t base)This takes a memory image and the file-relative address it corresponds to.
The one-argument form can be used to use the File API before the base is
known. Then set_base must be called before using the Memory API.
