# cymem: A Cython Memory Helper
|
|
|
|
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.
|
|
|
|
## Overview
|
|
|
|
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.
