# addchain: Rust crate for generating addition chains
## Usage
To find a short addition chain:
```rust
let chain = addchain::find_shortest_chain(num_bigint::BigUint::from(87u32));
```
To build the steps for an addition chain:
```rust
let steps = addchain::build_addition_chain(num_bigint::BigUint::from(87u32));
```
