Parser and evaluator for Accumulo Access Expressions for Rust and WASM

Accumulo Access for Rust

Introduction

This crate provides a Rust API for parsing and evaluating Accumulo Access Expressions, based on the AccessExpression specification.

Usage

Add the following to your Cargo.toml:

[dependencies]
accumulo-access = "0.1"

Example

use accumulo_access::check_authorization;

fn main() {
    let expr = "A&B&(C|D)";
    let auths = vec!["A", "B", "C"];
    let result = check_authorization(expr, auths);
    assert!(result.is_ok());
}

Limitations

• It doesn't limit the unicode ranges in quoted access tokens (ref. the specification).
• It doesn't have functionality for normalizing expressions (ref. the Java-based accumulo-access project).
• It doesn't have functionality for serializing expression trees to a string representation.

Known usages

• Accumulo Access extension for PostgreSQL
