Detailed Description

template<MdspanLike Mdspan, TensorAccessState AccessState>
requires std::is_const_v<typename Mdspan::element_type> && std::is_nothrow_move_constructible_v<Mdspan>
class uni20::read_mdspan_lease< Mdspan, AccessState >

Move-only RAII lease exposing one resolved read-only mdspan.

This lower-level lease intentionally carries no tensor storage policy or backend selector. The access state is stored before the mdspan so the mdspan is destroyed before access ends.

Template Parameters

Mdspan	Read-only resolved mdspan type.
AccessState	RAII state retaining the acquired data handle.
