Struct ParameterSpec 

pub struct ParameterSpec { /* private fields */ }

Value, unit, scale, bounds, and selection for one scalar.

Implementations

impl ParameterSpec

pub fn new( key: ParameterKey, value: f64, unit: impl Into<String>, bounds: ParameterBounds, scale: f64, refine: bool, ) -> Result<Self, ParameterError>

Validate and construct one scalar specification.

Errors

Returns ParameterError for non-finite values, empty units, out-of-bounds values, or non-positive/non-finite scales.

pub const fn key(&self) -> &ParameterKey

Borrow the stable parameter identity.

pub const fn value(&self) -> f64

Return the current physical value.

pub fn unit(&self) -> &str

Borrow the explicit unit label.

pub const fn bounds(&self) -> ParameterBounds

Return the physical bounds.

pub const fn scale(&self) -> f64

Return the positive solver scale.

pub const fn refine(&self) -> bool

Return whether this unconstrained parameter is selected.
