Function validate

pub fn validate(s: &mut Schema, rule: impl Into<Rule>) -> Result<(), Error>

Validate takes schema and applies a set of validation rules to it. The rules are stored on the top level under the “x-kubernetes-validations”.

use schemars::schema::Schema;
use kube::core::{Rule, Reason, Message, validate};

let mut schema = Schema::Object(Default::default());
let rule = Rule{
    rule: "self.spec.host == self.url.host".into(),
    message: Some("must be a URL with the host matching spec.host".into()),
    field_path: Some("spec.host".into()),
    ..Default::default()
};
validate(&mut schema, rule)?;
assert_eq!(
    serde_json::to_string(&schema).unwrap(),
    r#"{"x-kubernetes-validations":[{"fieldPath":"spec.host","message":"must be a URL with the host matching spec.host","rule":"self.spec.host == self.url.host"}]}"#,
);
