| Summary : Manage calls to calloc/free through Cython
|
Description :
cymem provides two small memory-management helpers for Cython. They make it
easy to tie memory to a Python object\'s life-cycle, so that the memory is freed
when the object is garbage collected.
The most useful is `cymem.Pool`, which acts as a thin wrapper around the calloc
function:
```python
from cymem.cymem cimport Pool
cdef Pool mem = Pool()
data1 = < int*>mem.alloc(10, sizeof(int))
data2 = < float*>mem.alloc(12, sizeof(float))
```
The `Pool` object saves the memory addresses internally, and frees them when the
object is garbage collected. Typically you\'ll attach the `Pool` to some cdef\'d
class. This is particularly handy for deeply nested structs, which have
complicated initialization functions. Just pass the `Pool` object into the
initializer, and you don\'t have to worry about freeing your struct at all —
all of the calls to `Pool.alloc` will be automatically freed when the `Pool`
expires.
