Struct MeshChanges 

pub struct MeshChanges {
    pub id: MeshId,
    pub changes: Option<ChangeSet>,
    pub placement_changed: bool,
    pub added: bool,
    pub removed: bool,
    pub colors_dirty: Option<Vec<VertexId>>,
    pub normals_dirty: Option<Vec<VertexId>>,
    pub fields_changed: Vec<FieldId>,
    pub sections_changed: Vec<SectionId>,
    pub channels_written: Vec<String>,
}

What happened to one mesh since the subscriber’s last Scene::take_changes_for (or Scene::take_changes for the default subscriber).

Fields

id: MeshId

The mesh. For a removed mesh this id no longer matches.

changes: Option<ChangeSet>

The merged changes of every commit, undo and redo since the last call. None means “treat everything as changed”: the mesh was added or compacted, or an undo or redo touching it failed with SceneError::Corrupted.

placement_changed: bool

True if the placement changed at any point since the last call, even if it was changed back.

added: bool

The mesh was added since the last call.

removed: bool

The mesh was removed since the last call.

colors_dirty: Option<Vec<VertexId>>

The vertices whose colours changed since the last call, ascending without duplicates. Some of an empty list when no colour changed; None means “every colour may have changed” (redraw them all).

normals_dirty: Option<Vec<VertexId>>

The vertices whose normals changed since the last call, with the same semantics as MeshChanges::colors_dirty: ascending without duplicates, None for “every normal may have changed”. Only reported while normals are on (see Scene::set_normals), apart from the None of an added or fully changed mesh.

fields_changed: Vec<FieldId>

The fields on this mesh whose values changed since the last call, each once.

sections_changed: Vec<SectionId>

The sections whose result for this mesh changed since the last call (recomputed to a different result, removed, or no longer selecting the mesh), each once, in the order first reported.

channels_written: Vec<String>

The channels written through Scene::derived_channel_mut, added with Scene::add_channel or removed with Scene::remove_channel, or dropped or restored as a whole by an edit, its undo or redo (ChangeSet::channels_toggled), since the last call, each name once, in the order first reported. A derived_channel_mut call counts as a write whether or not the slice is then written.
