[PATCH 14/16] sha1_file: implement `nth_packed_object_info`

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A new helper function allows to efficiently query the size and real type
of an object in a packfile based on its position on the packfile index.

This is particularly useful when trying to parse all the information of
an index in memory.
