pub const FORMAT_VERSION: u16 = 2;Expand description
The sekejap disk format, stamped into bytes 18-19 of every page.
Defined ONCE, here, because bytes 18-19 of a page are the only place the
number is written; sekejap_core::FORMAT_VERSION and
sekejap::FORMAT_VERSION are re-exports of this constant, not copies.
It is NOT meta::FORMAT_VERSION, which is the logical superblock version
of the inherited kernel Store (1 or 2, chosen by the compact-cells
cargo feature) and says what the pages of that store CONTAIN. This one is
the envelope: which sekejap disk format the file is. There is no v1 –
every sekejap from 0.17.0 writes and reads 2, an e4 pre-release file
carries 0 here, and a value that is not 2 is refused with the file
unchanged (docs/core/FORMAT_V2.md).
