Validation type and associated traits for error accumulation Validation types and utilities for accumulating errors.
This module provides the Validation type, which can accumulate multiple
errors while preserving success values. It’s particularly useful for validating
complex data structures where you want to collect all validation errors at once
rather than failing on the first error.
§Key Components
Validation- Core type that represents either a valid value or accumulated errors- Iterator adapters for traversing errors
- Trait implementations for composing validations
§Examples
use error_rail::validation::Validation;
let valid: Validation<String, i32> = Validation::Valid(42);
assert!(valid.is_valid());
let invalid: Validation<&str, i32> = Validation::invalid_many(["err1", "err2"]);
assert_eq!(invalid.iter_errors().count(), 2);
