Getters for the number of values stored in this node.

Wrapper to the underlying const map functions.

This checks that the variable is fixed.

Span::data() Returns a pointer to the span's underlying array of data (which is held outside the span).

\returns a const pointer to the array of the starting positions of the inner vectors. * This function is aimed at interoperability with other li

the memset function

Null `string_view` constructor

Span::begin() Returns an iterator pointing to the first element of this span, or `end()` if the span is empty.

Getter for the offset after the last value in the `values` array.

`InlinedVector::insert(...)` Inserts a copy of `v` at `pos`, returning an `iterator` to the newly inserted element.

This method returns 0. It is useful when 0 can be cast either as a pointer or as an integer value and thus lead to an ambiguous function call.

Get Array

`InlinedVector::size()` Returns the number of elements in the inlined vector.

Getter for the offset of the first value in the `values` array.

\returns a read-only view of the stored coefficients as a 1D array expression. * * \warning this method is for \b compressed \b storage \b

Returns a pointer to the underlying model storage. This API is for internal use only and regular users should have no need for it.

Overload of `string_view::find()` for finding a substring of a different C-style string `s` within the `string_view`.
