coord-rs's Introduction

pancake

A personal C++ utility library for a variety of uses

What does it do?

pancake includes many pieces of boilerplate code that are common throughout my software including:

Why the name 'pancake'?

I don't know. I searched "random words" online and 'pancake' was the first thing I saw. I'm not very inventive when it comes to names.

coord-rs's Issues

alloing &Vec3 + &Vec3

currently you have to dereference it explicitly

*x = *y  + *z

new maybe:

*x = y  + z

allow const creation of Vec

allow consts like:
const ENTITY_MIDDLE_OFFSET: Vec3<f32> = Vec3::new(0.0, 0.0, 0.9);

Add .div_euc() and .map() methods

add a map_vector method to iterate 2 vectors at once

if res.correction.x != 0.0 {
                        entity.vel_mut().x = 0.0;
                    }
                    if res.correction.y != 0.0 {
                        entity.vel_mut().y = 0.0;
                    }
                    if res.correction.z != 0.0 {
                        entity.vel_mut().z = 0.0;
                    }

if velocity.x.abs() / half_chunk_scale.x > speed_step_cnt {
            speed_step_cnt = velocity.x.abs() / half_chunk_scale.x;
        }
        if velocity.y.abs() / half_chunk_scale.y > speed_step_cnt {
            speed_step_cnt = velocity.y.abs() / half_chunk_scale.y;
        }
        if velocity.z.abs() / half_chunk_scale.z > speed_step_cnt {
            speed_step_cnt = velocity.z.abs() / half_chunk_scale.z;
        }

Use From<T> more often throughout the codebase

Add a .cast() method that uses FromPrimitive

Please mark the crate as deprecated on crates.io

I've implemented this package and looked what it would take to add a couple of features. I came to github and see it's intentionally no longer maintained. Could you please label this package as deprecated on crates.io. Thanks.

allow Vec3<f32> + Vec3<i64> addition

e.g. by having a easy (or implicit) conversion from Vec3 to Vec3

add elements that has ref access to elements

for better performance without copying. Same use-case than #7

coord is not actually no_std compatible

Despite being tagged on crates.io, coord is not no_std compatible because of a transitive dependency on std through the num-traits crate.

It looks like the continuous build is only building on Travis's default target (which I'm guessing is x86-64 linux?). Crates that set #[no_std] can still access the std crate if available. To test, try a bare metal target. For example:

$ rustup target add thumbv7em-none-eabihf
$ git clone https://github.com/zesterer/coord-rs.git
$ cd coord-rs
$ cargo build --target thumbv7em-none-eabihf

You'll get an error like the following:

    Checking rustc-serialize v0.3.24
    Checking rand v0.4.6
   Compiling num-iter v0.1.37

Allow creating vector from a single value

dot/cross products support?

Is it already available or planed?
