#[repr(C)]
pub struct my_decimal { pub _base: decimal_t, pub foo1: c_int, pub buffer: [decimal_digit_t; 9], pub foo2: c_int, }
Expand description

my_decimal class limits ‘decimal_t’ type to what we need in MySQL.

It contains internally all necessary space needed by the instance so no extra memory is needed. One should call fix_buffer_pointer() function when he moves my_decimal objects in memory.
