Compilation units
|
||
|
|
=================
|
||
|
|
|
||
|
|
When you run mypyc to compile a set of modules, these modules form a
|
||
|
|
*compilation unit*. Mypyc will use early binding for references within
|
||
|
|
the compilation unit.
|
||
|
|
|
||
|
|
If you run mypyc multiple times to compile multiple sets of modules,
|
||
|
|
each invocation will result in a new compilation unit. References
|
||
|
|
between separate compilation units will fall back to late binding,
|
||
|
|
i.e. looking up names using Python namespace dictionaries. Also, all
|
||
|
|
calls will use the slower Python calling convention, where arguments
|
||
|
|
and the return value will be boxed (and potentially unboxed again in
|
||
|
|
the called function).
|
||
|
|
|
||
|
|
For maximal performance, minimize interactions across compilation
|
||
|
|
units. The simplest way to achieve this is to compile your entire
|
||
|
|
program as a single compilation unit.
