Struct ExpressionBlender 

pub struct ExpressionBlender {
    pub anchors: Vec<(String, f32)>,
}

Interpolate between multiple named expressions using (name, weight) anchors.

This is a generalised barycentric blender: each anchor contributes its preset’s weights scaled by the anchor weight, then all contributions are summed and clamped.

Fields

anchors: Vec<(String, f32)>

(preset name, blending weight) pairs.

Implementations

impl ExpressionBlender

pub fn new() -> Self

Create a new blender with no anchors.

pub fn add_anchor(&mut self, name: String, weight: f32)

Add an anchor (preset name, weight).

pub fn evaluate(&self, library: &ExpressionLibrary) -> HashMap<String, f32>

Evaluate the blend against the given library.

Missing presets are silently skipped. Result is clamped to [0, 1].

pub fn normalize(&mut self)

Normalise anchor weights so they sum to 1.0.

If the total is zero the weights are left unchanged.

Trait Implementations

impl Clone for ExpressionBlender

fn clone(&self) -> ExpressionBlender

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionBlender

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

Formats the value using the given formatter.

impl Default for ExpressionBlender

fn default() -> Self

Returns the “default value” for a type.
