Struct ParameterLayout 

pub struct ParameterLayout { /* private fields */ }

Отображение параметров распределения на диапазоны в плоском beta-векторе.

Используется для introspection модели: распаковки коэффициентов, построения diagnostics и передачи информации внешним оптимизаторам.

Implementations

impl ParameterLayout

pub fn new(slices: Vec<ParameterSlice>) -> Self

Creates a layout from named slices.

pub fn len(&self) -> usize

Number of parameter blocks represented by this layout.

pub fn is_empty(&self) -> bool

true if this layout has no parameter blocks.

pub fn ncoefficients(&self) -> usize

Minimum coefficient-vector length needed to contain every slice.

For ordinary model layouts this is equal to the model’s coefficient count. For manually constructed layouts with gaps it returns the largest slice end.

pub fn slices(&self) -> &[ParameterSlice]

Returns all parameter slices in model order.

pub fn visit_slices(&self, visit: impl FnMut(usize, &'static str, Range<usize>))

Visits parameter slices in model order without allocating.

pub fn slice(&self, name: &str) -> Option<Range<usize>>

Returns the coefficient range for name, if present.

pub fn slice_of<P>(&self) -> Option<Range<usize>>

where P: ParameterName,

Returns the coefficient range for typed parameter marker P, if present.

Trait Implementations

impl Clone for ParameterLayout

fn clone(&self) -> ParameterLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterLayout

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

Formats the value using the given formatter.

impl Eq for ParameterLayout

impl PartialEq for ParameterLayout

fn eq(&self, other: &ParameterLayout) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
