Struct zng_app::render::ReferenceFrameId

pub struct ReferenceFrameId(/* private fields */);

Expand description

Represents an unique key for a spatial reference frame that is recreated in multiple frames.

The key can be generated from WidgetId, SpatialFrameId or FrameValueKey<PxTransform> all guaranteed to be unique even if the inner value of IDs is the same.

Implementations§

impl ReferenceFrameId

pub fn from_widget_child(parent_id: WidgetId, child_index: u32) -> Self

Key from WidgetId and u32 index.

This can be used in nodes that know that they are the only one rendering children nodes.

pub fn from_unique(id: SpatialFrameId) -> Self

Key from SpatialFrameId.

pub fn from_unique_child(id: SpatialFrameId, child_index: u32) -> Self

Key from SpatialFrameId and u32 index.

pub fn from_frame_value(frame_value_key: FrameValueKey<PxTransform>) -> Self

Key from a FrameValueKey<PxTransform>.

pub fn from_frame_value_child( frame_value_key: FrameValueKey<PxTransform>, child_index: u32, ) -> Self

Key from a FrameValueKey<PxTransform> and u32 index.
