partial_ref - Type checked partial references.

This crate provides type checked partial references for rust. Type checked partial references are one solution to solve interprocedural borrowing conflicts.

Example

```rust use partial_ref::*;

part!(pub Neighbors: Vec>); part!(pub Colors: Vec); part!(pub Weights: Vec);

[derive(PartialRefTarget, Default)]

pub struct Graph { #[part(Neighbors)] pub neighbors: Vec>, #[part(Colors)] pub colors: Vec, #[part(Weights)] pub weights: Vec, }

let mut g = Graph::default(); let mut gref = g.intopartialrefmut();

gref.partmut(Colors).extend(&[0, 1, 0]); gref.partmut(Weights).extend(&[0.25, 0.5, 0.75]);

gref.partmut(Neighbors).push(vec![1, 2]); gref.partmut(Neighbors).push(vec![0, 2]); gref.partmut(Neighbors).push(vec![0, 1]);

pub fn addcolortoweight( mut g: partial!(Graph, mut Weights, Colors), index: usize, ) { g.partmut(Weights)[index] += g.part(Colors)[index] as f32; }

let (neighbors, mut gref) = gref.splitpartmut(Neighbors); let (colors, mut gref) = gref.split_part(Colors);

for (edges, &color) in neighbors.iter_mut().zip(colors.iter()) { edges.retain(|&neighbor| colors[neighbor] != color);

for &neighbor in edges.iter() {
    add_color_to_weight(g_ref.borrow(), neighbor);
}

} ```
