This crate provides global configuration capabilities for `fastapi`.

## Config options

* Define rust type aliases for `fastapi` with `.alias_for(...)` method.
* Define schema collect mode for `fastapi` with `.schema_collect(...)` method.
  * `SchemaCollect:All` will collect all schemas from usages including inlined with `inline(T)`
  * `SchemaCollect::NonInlined` will only collect non inlined schemas from usages.

> [!WARNING]
> The build config will be stored to projects `OUTPUT` directory. It is then read from there via `OUTPUT` environment
> variable which will return **any instance** rust compiler might find at that time (Whatever the `OUTPUT` environment variable points to).
> **Be aware** that sometimes you might face a situation where the config is not aligned with your Rust aliases. 
> This might need you to change something on your code before changed config might apply.

## Install

Add dependency declaration to `Cargo.toml`.

```toml
[build-dependencies]
fastapi-config = "0.1"
```

## Examples

Create `build.rs` file with following content, then in your code you can just use `MyType` as 
alternative for `i32`.

```rust
use fastapi_config::Config;

fn main() {
    Config::new()
        .alias_for("MyType", "i32")
        .write_to_file();
}
```
