A graphql depth limit validation in Rust inspired by graphql_depth_limit
Add this to your Cargo.toml
:
[dependencies]
graphql_depth_limit = "0.1.1"
and this to your crate root (if you're using Rust 2015):
extern crate graphql_depth_limit;
Here's a simple example for verification of a graphql query:
use graphql_depth_limit::QueryDepthAnalyzer;
fn main() {
let query = r#"
query {
a {
b {
c
}
}
}
"#;
let depth = match QueryDepthAnalyzer::new(query, vec![], |_a, _b| true) {
Ok(validator) => validator.verify(5),
Err(val) => Err(DepthLimitError::Parse(val))
};
asssert_eq!(depth.ok()?, 3);
}
