Struct TransformRegistry 

pub struct TransformRegistry { /* private fields */ }

Registry for user-defined transforms.

Stores TransformDef objects that can be referenced by name in transform arrays. Supports parameterized transforms, keyframe animations, and transform cycling.

Implementations

impl TransformRegistry

pub fn new() -> Self

Create a new empty transform registry.

pub fn register(&mut self, transform: TransformDef)

Register a user-defined transform.

pub fn get(&self, name: &str) -> Option<&TransformDef>

Get a transform definition by name.

pub fn contains(&self, name: &str) -> bool

Check if a transform with the given name exists.

pub fn len(&self) -> usize

Get the number of registered transforms.

pub fn is_empty(&self) -> bool

Check if the registry is empty.

pub fn clear(&mut self)

Clear all transforms from the registry.

pub fn iter(&self) -> impl Iterator<Item = (&String, &TransformDef)>

Iterate over all transforms in the registry.

pub fn expand( &self, name: &str, params: &HashMap<String, f64>, frame: u32, total_frames: u32, ) -> Result<Vec<Transform>, TransformError>

Expand a user-defined transform for a specific frame.

If the transform is a simple ops-only transform, returns the ops directly. For keyframe animations, generates the appropriate transforms for the given frame. For cycling transforms, returns the transforms for the current cycle position.

Arguments

• name - The name of the user-defined transform
• params - Parameter values for parameterized transforms
• frame - Current frame number (for keyframe animations)
• total_frames - Total frames in the animation

pub fn expand_simple( &self, name: &str, params: &HashMap<String, f64>, ) -> Result<Vec<Transform>, TransformError>

Expand a simple (non-animated) user-defined transform.

For simple ops-only transforms, returns the ops. For keyframe animations, returns transforms for frame 0.

Trait Implementations

impl Clone for TransformRegistry

fn clone(&self) -> TransformRegistry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransformRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TransformRegistry

fn default() -> TransformRegistry

Returns the “default value” for a type.

impl Registry<TransformDef> for TransformRegistry

fn contains(&self, name: &str) -> bool

Check if an item with the given name exists in the registry.

fn get(&self, name: &str) -> Option<&TransformDef>

Get an item by name.

fn len(&self) -> usize

Get the number of items in the registry.

fn clear(&mut self)

Clear all items from the registry.

fn names(&self) -> Box<dyn Iterator<Item = &String> + '_>

Get an iterator over all names in the registry.

fn is_empty(&self) -> bool

Check if the registry is empty.
