ExprZ

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

enum Expr<A> {
    Atom(A),
    Group(Vec<Self>),
}

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
