Struct SqliteHeader 

pub struct SqliteHeader { /* private fields */ }

Sqlite header struct:

• The header of a sqlite3 database file is 100 bytes long (BOOM).
• Has a bunch of field that are listed below!
• IS BEING PARSED HERE BECAUSE AN OLD CODE I KNOW TO FIDDLE WITH SQLITE HEADERS

Sqlite header fields (from sqlite.org):

Offset	Size	Description
0	16	The header string: “SQLite format 3\000”
16	2	The database page size in bytes. Must be a power of two between 512 and 32768 inclusive, or the value 1 representing a page size of 65536.
18	1	File format write version. 1 for legacy; 2 for WAL.
19	1	File format read version. 1 for legacy; 2 for WAL.
20	1	Bytes of unused “reserved” space at the end of each page. Usually 0.
21	1	Maximum embedded payload fraction. Must be 64.
22	1	Minimum embedded payload fraction. Must be 32.
23	1	Leaf payload fraction. Must be 32.
24	4	File change counter.
28	4	Size of the database file in pages. The “in-header database size”.
32	4	Page number of the first freelist trunk page.
36	4	Total number of freelist pages.
40	4	The schema cookie.
44	4	The schema format number. Supported schema formats are 1, 2, 3, and 4.
48	4	Default page cache size.
52	4	The page number of the largest root b-tree page when in auto-vacuum or incremental-vacuum modes, or zero otherwise.
56	4	The database text encoding. A value of 1 means UTF-8. A value of 2 means UTF-16le. A value of 3 means UTF-16be.
60	4	The “user version” as read and set by the user_version pragma.
64	4	True (non-zero) for incremental-vacuum mode. False (zero) otherwise.
68	4	The “Application ID” set by PRAGMA application_id.
72	20	Reserved for expansion. Must be zero.
92	4	The version-valid-for number.
96	4	SQLITE_VERSION_NUMBER
