Struct sqlite_rs::header::PageSize

pub struct PageSize(/* private fields */);

Page Size (2 Bytes)

The two-byte value beginning at offset 16 determines the page size of the database. For SQLite versions 3.7.0.1 (2010-08-04) and earlier, this value is interpreted as a big-endian integer and must be a power of two between 512 and 32768, inclusive. Beginning with SQLite version 3.7.1 (2010-08-23), a page size of 65536 bytes is supported. The value 65536 will not fit in a two-byte integer, so to specify a 65536-byte page size, the value at offset 16 is 0x00 0x01. This value can be interpreted as a big-endian 1 and thought of as a magic number to represent the 65536 page size. Or one can view the two-byte field as a little endian number and say that it represents the page size divided by 256. These two interpretations of the page-size field are equivalent.
