## Migration Guide

### Overview
Most of the breaking changes introduced in this version primarily impact
developers who implement their own images. For general usage, the API
remains mostly the same, with some improvements and enhancements for
better performance and flexibility.

### 1. Renaming of `RunnableImage`
- **Old**: `RunnableImage`
- **New**: `ContainerRequest`
- **Update**: The explicit conversion from `Image` to `ContainerRequest`
(formerly `RunnableImage`) is no longer necessary. Instead, you can now
directly import `testcontainers::ImageExt` and override image parameters
as needed.

### 2. Changes to `Image` Methods
- **Method**: `Image::tag` and `Image::name`
  - **Old Return Type**: `String`
  - **New Return Type**: `&str`
- **Update**: Update any code that relies on these methods to handle the
new return type `&str`. This change helps improve performance by
avoiding unnecessary allocations.

### 3. Changes to `Image::exposed_ports`
- **Method**: `Image::exposed_ports`
- **Old Return Type**: Implementation-specific or previously different.
  - **New Return Type**: `&[ContainerPort]`
- **Update**: The method now returns a slice of `ContainerPort`, which
supports exposing ports with protocols `TCP`, `UDP`, and `SCTP`. Update
your code to handle the slice accordingly.

### 4. Removal of Associated Type `Args` in `Image`
- **Old**: `Image` had an associated type `Args`.
- **New**: The associated type `Args` is removed.
- **Update**: Command arguments are now part of `Image::cmd`, which
returns `impl IntoIterator<Item = impl Into<String>>`. This change
allows more flexibility in specifying command arguments. Ensure your
code is updated to work with the new method signature.

### 5. Simplification of Trait Implementation in `Image`
- **Old**: `Image` required `Box<dyn ..>` for certain traits.
- **New**: Utilizes Return Position `impl` Trait in Trait (RPITIT).
- **Update**: Instead of requiring `Box<dyn ..>`, `Image` now uses
RPITIT for trait returns. This change simplifies the code and improves
readability and performance. Familiarize yourself with
[RPITIT](https://rustc-dev-guide.rust-lang.org/return-position-impl-trait-in-trait.html)
to understand its benefits and applications in your implementation.

### 6. Changes to `RunnableImage::with_mapped_port`
- **Old**: `RunnableImage::with_mapped_port`
- **New**: Accessible through `ImageExt::with_mapped_port`
- **Update**: This method now accepts two parameters instead of a tuple.
Adjust your method calls to pass the parameters separately.
