Type Alias mdb_size_t

pub type mdb_size_t = usize;

Unsigned type used for mapsize, entry counts and page/transaction IDs.

It is normally size_t, hence the name. Defining MDB_VL32 makes it
uint64_t, but do not try this unless you know what you are doing.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
