Function form_validation::concat_results

pub fn concat_results<Key>(
    results: Vec<Result<(), ValidationErrors<Key>>>
) -> Result<(), ValidationErrors<Key>> where
    Key: PartialEq + Clone, 

Join validation results, concatinating any errors they may contain. If any of the results are an Err it will return an Err containing all the errors from all th results.

Example

use form_validation::{concat_results, ValidationError, ValidationErrors};
let results = vec![
    Ok(()),
    Err(ValidationErrors::new(vec![ValidationError::new("field1")])),
    Err(ValidationErrors::new(vec![ValidationError::new("field1")])),
    Err(ValidationErrors::new(vec![ValidationError::new("field2")])),
];

let result = concat_results(results);

let errors = result.unwrap_err();

assert_eq!(3, errors.len());

let field1_errors = errors.get(&"field1").unwrap();
assert_eq!(2, field1_errors.len());

let field2_errors = errors.get(&"field2").unwrap();
assert_eq!(1, field2_errors.len());
