This README is abbreviated and applies to using clay in Zig specifically: If you haven't taken a look at the [full documentation for clay](https://github.com/nicbarker/clay/blob/main/README.md), it's recommended that you take a look there first to familiarise yourself with the general concepts.
The **most notable difference** between the C API and the Zig bindings is that opening and closing the scope for declaring child elements must be done "manually" using 2 function calls.
other changes include:
Some differences between the C API and the Zig bindings include:
- minor naming changes
- ability to initialize a parameter by calling a function that is part of its type's namespace for example `.fixed()` or `.layout()`
- ability to initialize a parameter by using a public constant that is part of its type's namespace for example `.grow`
