The C++ Standard Template Library (STL) for Python

CSTL : The C++ Standard Template Library (STL) for Python

In the CSTL tool, we wrap several C++ STL containers for use in Python. The containers use native C++ implementation and will not have the Copy on write problem like native list, dict in Python.

Install

Install from pip:

pip install CSTL

Build from source:

git clone https://github.com/fuzihaofzh/CSTL
cd CSTL
./build.sh
python setup.py install

Usage

import CSTL
vec = CSTL.VecInt([1,2,3,4,5,6,7])
print(vec[2])      #3
vec[2] = 1
print(vec[2])      #1
vec.append(10)
print(vec[-1])     #10
print(list(vec))   #[1, 2, 1, 4, 5, 6, 7, 10]

Supported Datatype

We support the following data types as the elements in the containers

Python Type	C++ Type	Can be dict key
int	int	Yes
int	std::int64	Yes
str	std::string	Yes
float	float	No
double	double	No
bool	bool	No

Supported Containers

The supported containers are listed as follows

Python Structure	C++ Container
list	std::vector
dict	std::unordered_map
set	std::unordered_set

We also support nested container, namely, structure like std::unordered_map< std::string,std::unordered_map< std::string,std::vector< bool > > > is supported. Currently, at most 3 nested layers are supported.
