**Fault Tolerance**: `FaultTolerantClient` wrapper (retry, circuit breaker), `SwitchableHttpClient` for HTTP client fallback

## Key Components

### Core Classes

- **Crawler** (`Crawler.java`): Main orchestrator - `execute()`, `addUrl()`, `cleanup()`, `stop()`

## Number validations: greater than and less than or equal { #number-validations-greater-than-and-less-than-or-equal }

The same applies for:

* `gt`: `g`reater `t`han
* `le`: `l`ess than or `e`qual

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py310.py hl[10] *}

## Number validations: floats, greater than and less than { #number-validations-floats-greater-than-and-less-than }

        float | None,
        Doc(
            """
            Greater than. If set, value must be greater than this. Only applicable to
            numbers.

## Sayı Doğrulamaları: Büyük ve Küçük Eşit { #number-validations-greater-than-and-less-than-or-equal }

Aynısı şunlar için de geçerlidir:

* `gt`: `g`reater `t`han
* `le`: `l`ess than or `e`qual

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py310.py hl[10] *}

## Sayı Doğrulamaları: `float` Değerler, Büyük ve Küçük { #number-validations-floats-greater-than-and-less-than }

Те саме застосовується до:

* `gt`: `g`reater `t`han
* `le`: `l`ess than or `e`qual

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py310.py hl[10] *}

## Валідація числових даних: float, більше ніж і менше ніж { #number-validations-floats-greater-than-and-less-than }

То же самое применимо к:

* `gt`: больше (`g`reater `t`han)
* `le`: меньше или равно (`l`ess than or `e`qual)

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py310.py hl[10] *}

## Валидация числовых данных: числа с плавающей точкой, больше и меньше { #number-validations-floats-greater-than-and-less-than }

    The first part is the `scheme`, the second part is the `credentials`.

    For example, in an HTTP Bearer token scheme, the client will send a header
    like:

    ```
    Authorization: Bearer deadbeef12346
    ```

    In this case:

    * `scheme` will have the value `"Bearer"`
    * `credentials` will have the value `"deadbeef12346"`
