Detailed Description

template<MutableMdspanLike Mdspan, TensorAccessState AccessState>
requires std::is_nothrow_move_constructible_v<Mdspan>
class uni20::write_mdspan_lease< Mdspan, AccessState >

Move-only RAII lease exposing one resolved writable 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	Writable resolved mdspan type.
AccessState	RAII state retaining the acquired data handle.
