Returns the byte offset corresponding to a list of rank() indices into the layout.

Unlike for operator[], the number of indices must equal rank().

Parameters:¶

const Indices &indices¶

const Index (&indices)[N]

A list of rank() indices. span(indices) must be valid, and the resulting span::value_type must be convertible to Index. May be specified as a braced list, e.g. layout({1, 2, 3}).

Pre:¶

0 <= span(indices)[i] < shape()[i] for 0 <= i < rank()

Checks:¶

span(indices).size() == rank()

Returns:¶

sum(byte_strides[i] * indices[i] for 0 <= i < rank())
