Module assembly_fdb::file

The structures, as they are serialized

This module contains the low-level structs that make up the FDB file. These structures are annotated with #[repr(C)] and can be used to read directly from a memory-mapped file on a little-endian machine.

Not all values of these structs are valid for FDB files, but all well-formed FDB-files can be represented by these values. Most importantly, the FDBColumnHeader::column_data_type only has a limited amount of defined values but covers the whole 32 bits.
