// Shim for ORT's core/common/narrow.h — used by the vendored MLAS (cast.cpp).
|
|
// Upstream provides a checked narrowing cast a la gsl::narrow. The MLAS
|
|
// translation units here only #include the header; they do not actually
|
|
// invoke narrow<T>(...). We provide a minimal definition anyway so the file
|
|
// compiles cleanly and any future MLAS update that does call narrow keeps
|
|
// working.
|
|
//
|
|
// This file is intentionally tiny so OpenCV can keep a stable shim while
|
|
// upstream MLAS evolves.
