# Objective - Provide better compile-time errors and diagnostics. - Add more options to allow more textures types and sampler types. - Update array_texture example to use upgraded AsBindGroup derive macro. ## Solution Split out the parsing of the inner struct/field attributes (the inside part of a `#[foo(...)]` attribute) for better clarity Parse the binding index for all inner attributes, as it is part of all attributes (`#[foo(0, ...)`), then allow each attribute implementer to parse the rest of the attribute metadata as needed. This should make it very trivial to extend/change if needed in the future. Replaced invocations of `panic!` with the `syn::Error` type, providing fine-grained errors that retains span information. This provides much nicer compile-time errors, and even better IDE errors.  Updated the array_texture example to demonstrate the new changes. ## New AsBindGroup attribute options ### `#[texture(u32, ...)]` Where `...` is an optional list of arguments. | Arguments | Values | Default | |-------------- |---------------------------------------------------------------- | ----------- | | dimension = "..." | `"1d"`, `"2d"`, `"2d_array"`, `"3d"`, `"cube"`, `"cube_array"` | `"2d"` | | sample_type = "..." | `"float"`, `"depth"`, `"s_int"` or `"u_int"` | `"float"` | | filterable = ... | `true`, `false` | `true` | | multisampled = ... | `true`, `false` | `false` | | visibility(...) | `all`, `none`, or a list-combination of `vertex`, `fragment`, `compute` | `vertex`, `fragment` | Example: `#[texture(0, dimension = "2d_array", visibility(vertex, fragment))]` ### `#[sampler(u32, ...)]` Where `...` is an optional list of arguments. | Arguments | Values | Default | |----------- |--------------------------------------------------- | ----------- | | sampler_type = "..." | `"filtering"`, `"non_filtering"`, `"comparison"`. | `"filtering"` | | visibility(...) | `all`, `none`, or a list-combination of `vertex`, `fragment`, `compute` | `vertex`, `fragment` | Example: `#[sampler(0, sampler_type = "filtering", visibility(vertex, fragment)]` ## Changelog - Added more options to `#[texture(...)]` and `#[sampler(...)]` attributes, supporting more kinds of materials. See above for details. - Upgraded IDE and compile-time error messages. - Updated array_texture example using the new options. |
