graphqldepthlimit

A graphql depth limit validation in Rust inspired by graphqldepthlimit

Add this to your Cargo.toml:

toml [dependencies] graphql_depth_limit = "0.1.0"

and this to your crate root (if you're using Rust 2015):

rust extern crate graphql_depth_limit;

Here's a simple example for verification of a graphql query:

```rust use regex::Regex;

fn main() { let query = r#" query { a { b { c } } } "#; let depth = match QueryDepthAnalyzer::new(query, vec![], |a, _b| true) { Ok(validator) => validator.verify(limit), Err(val) => Err(DepthLimitError::Parse(val)) }; assserteq!(depth.ok()?, 3); } ```
