Crate python

Expand description

Rust Python Objects

use python like objects in rust, such as list, for now.

have the simplicity and performance together.

be happy.

Showcase - python list

// the crate name is 'python-objects'
// because there is another crate out there with `python` name
// but the lib.rs (library crate of this crate) its called `python`
// so you can import like this
extern crate python;
// actually 'extern crate' is useless
// just use only 'use python::'

// use everything from python
use python::*;

fn main() {
    // create a new python list
    let mut python_list =
        List::from(String::from("123123"));
    // at this point the list will look like this
    // ['1', '2', '3', '1', '2', '3']

    // append an integer
    python_list.append_back(123);
    // append a rust static string
    python_list.append_front("hello");
    python_list.append_back(123);
    // append a list
    python_list.append_back(List::from(String::from("working")));
    // note that the python list supports another python list inside

    // append a float
    python_list.append_back(123.123);
    python_list.append_back(123.123);
    python_list.append_back(123.123);
    // append a rust String
    python_list.append_back(String::from("asdasd"));

    python_list.append_back(
        List::from("something".to_string()));

    // append a python string
    // note that this _String is from this crate
    // its the struct that handles the String and &str data types
    python_list.append_back(
        _String::from(
            String::from("python string")));

    // append a python bool
    // note that Bool is the python struct that handles rust's bool
    python_list.append_back(Bool::new(true));
    python_list.append_back(Bool::new(false));
    // append a rust bool
    python_list.append_back(false);

    // print just like in python
    print(&python_list);

    // use len just like in python
    print(len(&python_list));


    // python_list.append_front("salutare");

    // iterate over the list just like in python
    // there are plans for future to remove the .iter()
    // so you can use for o in python_list { ... }, just that simple
    for o in python_list.iter() {
        print(o)
    }

    // create a python from parsing a static string
    let list_from_str = "123123".parse::<List>().unwrap();
    print(&list_from_str);


    let iter = (0..5).into_iter();
    // let list_from_iterator: List = iter.collect();

    // create a python list from rust iterator
    let list_from_iterator = iter.collect::<List>();
    print(&list_from_iterator);
}

output

['hello', '1', '2', '3', '1', '2', '3', 123, 123, ['w', 'o', 'r', 'k', 'i', 'n', 'g'], 123.123, 123.123, 123.123, 'asdasd', ['s', 'o', 'm', 'e', 't', 'h', 'i', 'n', 'g'], 'python string', True, False, False]

as you can see the list contains char, float (f32), integer (i32), a rust string, another python list, a python string and many more data types.

this is just bare bones and experimental, more features will come soon. stay still!

Structs

Bool

Bool structure for True and False

Char

Char struct that handles rust char

Dict

Dict struct that represents the python dict

Float

Float struct that handles f32 and f64

Int

Int struct, holds and _integer: i32

List

the main component

_String

the struct that handles String and &str

Enums

Object

supreme enum

Traits

Append

append function for List can append any data type

AppendFront

appends to front of the list meaning: list.insert(o, item)

Extend

extend the current list with anything

Iterable

implement iterable for List for example i need this to use with max min builtins

SetItem

_Hashable

_Object

the supreme _Object trait that its derived types should implement like all the functions from python

Functions

_str

_str(object); sorry but i cant name this ‘str’ because there is a rust data type called string slice which is called guess: str that remains the convension

print(object);

len(object);

print(object);

print(object);

repr(object);

get the type of an object
