You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: validation.rs
    path of file: ./repos/qdrant/lib/collection/src/operations
    
    the code of the file until where you have to start completion: use actix_web_validator::error::flatten_errors;
use serde_json::Value;
use validator::{ValidationError, ValidationErrors};

/// Warn about validation errors in the log.
///
/// Validation errors are pretty printed field
    
    fn test_config_validation_render() {
        let bad_config = OtherThing {
            things: vec![
                SomeThing { idx: 0 },
                SomeThing { idx: 1 },
                SomeThing { idx: 2 },
            ],
        };

        let errors = bad_config
            .validate()
            .expect_err("validation of bad config should fail");

        assert_eq!(
            describe_errors(&errors),
            vec![(
                "things[0].idx".into(),
                "value 0 invalid, must be 1.0 or larger".into()
            )]
        );
    }
