_An Expression Library_



## About

_ExprZ_ is an expression representation and parsing library. _ExprZ_ expressions are typed s-expressions formed from atoms or groups of expressions and represent enumerated types of the form

```rust

enum Expr {

    Atom(A),

    Group(Vec),

}

```


_ExprZ_ generalizes this `enum` by defining an `Expression` trait which encompasses the algebraic properties of the above `enum` but which affords the user the flexibility of a more efficient implementation.

_ExprZ_ comes with default implementations of `Expression` which use the Rust `alloc` library. To access these implementations use the `alloc` feature on the crate.

### Rust Nightly

The most recent version of _ExprZ_ uses the Rust nightly compiler toolchain which is necessary for defining the main `Expression` trait. In the future we hope to remove this requirement as the `Expression` API becomes more refined over time or once the standard compiler toolchain catches up.

## Getting Started

For more information on how to use _ExprZ_, see the [documentation](https://docs.rs/exprz).
