//! This module defines helper functions for loading fixtures in tests.
//!
//! The `read_fixture` function reads a fixture file from the `src/fixtures` directory relative to the Cargo manifest directory. The function takes a `name` argument that specifies the name of the fixture file to read. The function returns a `Result` containing the contents of the fixture file as a `String`.
//!
//! The `read_fixture_as` function is a generic function that reads a fixture file and deserializes its contents into a value of type `T`. The function takes a `name` argument that specifies the name of the fixture file to read, and a type parameter `T` that specifies the type to deserialize the fixture contents into. The function returns a `Result` containing the deserialized value.
//!
//! Both functions return an `anyhow::Result`, which allows for easy error handling using the `?` operator. The functions are intended to be used in tests to load fixture data for testing purposes.
