//
// This file implements a light-weight runtime support library for
// manipulating sparse tensors from MLIR. More specifically, it provides
// C-API wrappers so that MLIR-generated code can call into the C++ runtime
// support library. The functionality provided in this library is meant
// to simplify benchmarking, testing, and debugging of MLIR code operating
// on sparse tensors. However, the provided functionality is **not**
// part of core MLIR itself.
//
// The following memory-resident sparse storage schemes are supported:
//
// (a) A coordinate scheme for temporarily storing and lexicographically
// sorting a sparse tensor by coordinate (SparseTensorCOO).
//
// (b) A "one-size-fits-all" sparse tensor storage scheme defined by
// per-dimension sparse/dense annnotations together with a dimension
// ordering used by MLIR compiler-generated code (SparseTensorStorage).
//
// The following external formats are supported:
//
// (1) Matrix Market Exchange (MME): *.mtx
// https://math.nist.gov/MatrixMarket/formats.html
//
// (2) Formidable Repository of Open Sparse Tensors and Tools (FROSTT): *.tns
// http://frostt.io/tensors/file-formats.html
//
// Two public APIs are supported:
//
// (I) Methods operating on MLIR buffers (memrefs) to interact with sparse
// tensors. These methods should be used exclusively by MLIR
// compiler-generated code.
//
// (II) Methods that accept C-style data structures to interact with sparse
// tensors. These methods can be used by any external runtime that wants
// to interact with MLIR compiler-generated code.
//
// In both cases (I) and (II), the SparseTensorStorage format is externally
// only visible as an opaque pointer.
