Constructor & Destructor Documentation

FuncStructInfo()

tvm::relax::FuncStructInfo::FuncStructInfo	(	Array< StructInfo >	params,
		StructInfo	ret,
		bool	purity = true,
		Span	span = Span()
	)

Constructor from parameter struct info and return value struct info.

Parameters

params	The struct info of function parameters.
ret	The return value struct info.
purity	The purity of the function (true by default).
span	The span of the AST.

Note

If the ret contains variables(tir::Var and relax::Var), they must be deducible from params. If you are unsure, you can always erase ret to static.

Member Function Documentation

OpaqueFunc() [1/2]

static FuncStructInfo tvm::relax::FuncStructInfo::OpaqueFunc ( StructInfo  ret = ObjectStructInfo(), bool  purity = false, Span  span = Span()  )

static

Construct an opaque function using from return struct info.

Parameters

ret	The struct info of the return value.
purity	The purity of the function (false by default: most external functions are not pure).
span	The span of the AST.

Returns

The FuncStructInfo for opaque packedfunc.

Note

Defaults to an derive func that always return ObjectStructInfo if not specified.

OpaqueFunc() [2/2]

static FuncStructInfo tvm::relax::FuncStructInfo::OpaqueFunc ( StructInfoDeriveFunc  derive_func, bool  purity = false, Span  span = Span()  )

static

Constructing an opaque function struct info using derive_func.

Parameters

derive_func	Derivation function.
purity	The purity of the function (false by default: most external functions are not pure).
span	The span of the AST.

Returns

The FuncStructInfo for opaque packedfunc.

Note

Defaults to an derive func that always return ObjectStructInfo if not specified.
