Use any characters as your own numeric base and convert to and from decimal.
_There is also a Ruby and Crystal implementation of this which this was based off of._
### Installation
Add the following to your Cargo.toml file
```toml
[dependencies]
base_custom = "0.1.0"
```
To include it for usage add
```rust
extern crate base_custom;
use base_custom::BaseCustom;
```
to your file.
### Usage
```rust
// Binary with no delimiter
let base2 = BaseCustom::<char>::new("01".chars().collect());
assert_eq!(base2.decimal("00001"), 1_u32);
assert_eq!(base2.decimal("100110101"), 309_u32);
assert_eq!(base2.gen(340), "101010100");
assert_eq!(base2.gen(0xF45), "111101000101");
assert_eq!(base2.gen(0b111), "111");
// Trinary with no delimiter
let base3 = BaseCustom::<char>::new("ABC".chars().collect());
assert_eq!(base3.decimal("ABC"), 5);
assert_eq!(base3.gen(123), "BBBCA");
// Custom base like Musical Chords and a space delimiter
let base_music = BaseCustom::<String>::new("A A# B C C# D D# E F F# G G#", Some(' '));
assert_eq!(base_music.decimal("F F# B D# D A# D# F# "), 314159265);
assert_eq!(base_music.gen(314159265), "F F# B D# D A# D# F# ");
```
When using `BaseCustom::<String>::new` the second parameter must be of `Option<char>` to
choose your optional delimiter.
