Expand description

The difference between two ParamState values.

Fields§

§d_height: f32§d_weight: f32§d_muscle: f32§d_age: f32§extra_changes: Vec<(String, f32, f32)>

Extra keys that changed: (key, old_value, new_value).

§extra_added: Vec<(String, f32)>

Extra keys added in b (not present in a).

§extra_removed: Vec<(String, f32)>

Extra keys removed in b (present in a but not b).

Implementations§

Source §

impl ParamDiff

Source

pub fn compute(a: &ParamState, b: &ParamState) -> Self

Compute the diff: b - a for each field.

Source

pub fn is_zero(&self, tolerance: f32) -> bool

True if all diffs are (near) zero.

Source

pub fn magnitude(&self) -> f32

L2 norm of the numeric diffs (height, weight, muscle, age).

Source

pub fn apply(&self, a: &ParamState) -> ParamState

Apply the diff to a ParamState: a + diff = b.

Source

pub fn scaled(&self, factor: f32) -> ParamDiff

Scale the diff by a factor.

Source

pub fn describe(&self, threshold: f32) -> String

Human-readable description of what changed.
