Accumulo Access for Rust

Introduction

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

Quickstart

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());
}

Functionality

• Using the equivalent method in caching::check_authorization will memoize/cache the result based on the input (expression+authorization tuple).
• Possibility to return parsed expression as an expression tree; either as a serde JSON Value-based tree, or a JSON string representation.

Known usages

• Accumulo Access extension for PostgreSQL
