Async Data Validator

A library for validating streams of data from async sources with boolean checks.

Capabilities

Validate all items pass checks

Implement validation that checks if all items in an async stream satisfy given criteria.

• When checking async iterable [1, 2, 3, 4], validate_all_positive returns True @test
• When checking async iterable [1, -2, 3], validate_all_positive returns False @test
• When checking empty async iterable, validate_all_positive returns True @test

Validate any item passes checks

Implement validation that checks if any item in an async stream satisfies given criteria.

• When checking async iterable [1, 2, 3] with validator that accepts even numbers, validate_any_valid returns True @test
• When checking async iterable [1, 3, 5] with validator that accepts even numbers, validate_any_valid returns False @test
• When checking empty async iterable with any validator, validate_any_valid returns False @test

Validate with async predicates

Support validation using async predicate functions for complex checks.

• When checking async iterable ["apple", "banana"] with async predicate that checks string length > 3, validate_all_with_predicate returns True @test
• When checking async iterable ["hi", "hello"] with async predicate that checks string length > 3, validate_all_with_predicate returns False @test

    Check if all items in an async iterable satisfy an async predicate.

    Args:

        predicate: An async function that returns True/False for each item

    Returns:
        True if all items satisfy the predicate, False otherwise
