Struct RenderResources 

pub struct RenderResources {
    pub sampler: Option<Sampler>,
    pub sampler_nearest: Option<Sampler>,
    pub uniform_buffer: Option<UniformBuffer>,
    pub nearest_common_bind_group: Option<BindGroup>,
    pub image_bind_groups: HashMap<TextureId, BindGroup>,
    pub image_bind_group_layout: Option<BindGroupLayout>,
}

Shared render resources

This corresponds to the RenderResources struct in the C++ implementation. Contains samplers, uniform buffers, and bind group layouts that are shared across all frames.

Fields

sampler: Option<Sampler>

Linear texture sampler

sampler_nearest: Option<Sampler>

Nearest/point texture sampler

uniform_buffer: Option<UniformBuffer>

Uniform buffer manager (also owns the common bind group layout)

nearest_common_bind_group: Option<BindGroup>

Common bind group using the nearest/point sampler

image_bind_groups: HashMap<TextureId, BindGroup>

Image bind groups cache (texture_id -> bind_group)

image_bind_group_layout: Option<BindGroupLayout>

Image bind group layout (cached for efficiency)
