Add ability to parse pdb info from PE file #298
Conversation
Just like we can get the UUID from macho files and the build-id from ELF files, this change allows users to pull out the PDB info (path, age, and GUID) from PE files. macho and ELF files will return `Ok(None)`

Should this be [u8; 16]
?
I also considered the existing pe::Guid
but I don't think its definition is great. Maybe it should be [u8; 16]
too.

Yea, I think [u8; 16]
makes sense. I believe the definition of the GUID is well defined as 16 bytes. According to Microsoft's definition at least. I'll change to [u8; 16]
.
I also considered the existing
pe::Guid
Oh woah, I did not see this on my first pass. I'm happy to use pe::Guid
or convert pe::Guid
to be a [u8; 16]
. The technical definition from Microsoft's definition is what is currently defined for pe::Guid
. I'm happy to use that.

Let's change it from a reference to a value too, the size of this struct isn't significant.

I can definitely do that, but I'm curious what benefit this brings? The path
value will still need to be a reference with a lifetime of 'data
unless we want to copy that as well meaning this struct will still need to have the 'data
lifetime.

For consistency with mach_uuid
, and for the incredibly minor benefit that the user doesn't need to dereference it. I think UUIDs are like a primitive type that you normally pass around by value, not by reference. e.g. if we were reading a u128
, then you'd probably expect that to be passed by value.

Makes sense, thanks for the explanation!
