Struct PrimitiveComparer 

pub struct PrimitiveComparer<'a> {
    prev: &'a CachedSurfaceDescriptor,
    curr: &'a CachedSurfaceDescriptor,
    resource_cache: &'a ResourceCache,
    opacity_bindings: &'a FastHashMap<PropertyBindingId, BindingInfo<f32>>,
    color_bindings: &'a FastHashMap<PropertyBindingId, BindingInfo<ColorU>>,
}

A helper struct to compare a primitive and all its sub-dependencies.

Fields

prev: &'a CachedSurfaceDescriptor

curr: &'a CachedSurfaceDescriptor

resource_cache: &'a ResourceCache

opacity_bindings: &'a FastHashMap<PropertyBindingId, BindingInfo<f32>>

color_bindings: &'a FastHashMap<PropertyBindingId, BindingInfo<ColorU>>

Implementations

impl<'a> PrimitiveComparer<'a>

pub fn new( prev: &'a CachedSurfaceDescriptor, curr: &'a CachedSurfaceDescriptor, resource_cache: &'a ResourceCache, opacity_bindings: &'a FastHashMap<PropertyBindingId, BindingInfo<f32>>, color_bindings: &'a FastHashMap<PropertyBindingId, BindingInfo<ColorU>>, ) -> Self

pub fn compare_prim( &mut self, prev_desc: &PrimitiveDescriptor, curr_desc: &PrimitiveDescriptor, ) -> PrimitiveCompareResult

Compares two primitive descriptors using prim_uid + quantized raster-space vert corners. Transform changes are covered by vert corners; dynamic content changes (images, opacity/color bindings) are checked via the dep stream.
