Typedef Documentation

MR_std_optional_std_string

typedef struct MR_std_optional_std_string MR_std_optional_std_string

Stores either a single std::string or nothing. Supported MR_PassBy modes: MR_PassBy_DefaultConstruct, MR_PassBy_Copy, MR_PassBy_Move, (and MR_PassBy_DefaultArgument and MR_PassBy_NoObject if supported by the callee).

MR_std_string

typedef struct MR_std_string MR_std_string

Function Documentation

MR_std_optional_std_string_AssignFrom()

MRC_API void MR_std_optional_std_string_AssignFrom	(	MR_std_optional_std_string *	_this,
		const char *	other,
		const char *	other_end )

Assigns the contents. Parameter _this can not be null. It is a single object. If other_end is null, then other is assumed to be null-terminated. Non-null other_end requires a non-null other. Parameter other is optional. To keep it empty, pass a null pointer to both it and other_end.

MR_std_optional_std_string_AssignFromAnother()

MRC_API void MR_std_optional_std_string_AssignFromAnother	(	MR_std_optional_std_string *	_this,
		MR_PassBy	other_pass_by,
		MR_std_optional_std_string *	other )

Assigns the contents from another instance. Both objects remain alive after the call. Parameter _this can not be null. It is a single object.

MR_std_optional_std_string_ConstructFrom()

MRC_API MR_std_optional_std_string * MR_std_optional_std_string_ConstructFrom	(	const char *	other,
		const char *	other_end )

Constructs a new instance. If other_end is null, then other is assumed to be null-terminated. Non-null other_end requires a non-null other. Parameter other is optional. To keep it empty, pass a null pointer to both it and other_end. Never returns null. Returns an instance allocated on the heap! Must call MR_std_optional_std_string_Destroy() to free it when you're done using it.

MR_std_optional_std_string_ConstructFromAnother()

MRC_API MR_std_optional_std_string * MR_std_optional_std_string_ConstructFromAnother	(	MR_PassBy	other_pass_by,
		MR_std_optional_std_string *	other )

Constructs a copy of another instance. The source remains alive. Never returns null. Returns an instance allocated on the heap! Must call MR_std_optional_std_string_Destroy() to free it when you're done using it.

MR_std_optional_std_string_DefaultConstruct()

MRC_API MR_std_optional_std_string * MR_std_optional_std_string_DefaultConstruct

(

void

)

Constructs an empty (default-constructed) instance. Never returns null. Returns an instance allocated on the heap! Must call MR_std_optional_std_string_Destroy() to free it when you're done using it.

MR_std_optional_std_string_DefaultConstructArray()

MRC_API MR_std_optional_std_string * MR_std_optional_std_string_DefaultConstructArray

(

size_t

num_elems

)

Constructs an array of empty (default-constructed) instances, of the specified size. Will never return null. The array must be destroyed using MR_std_optional_std_string_DestroyArray(). Use MR_std_optional_std_string_OffsetMutablePtr() and MR_std_optional_std_string_OffsetPtr() to access the array elements.

MR_std_optional_std_string_Destroy()

MRC_API void MR_std_optional_std_string_Destroy

(

const MR_std_optional_std_string *

_this

)

Destroys a heap-allocated instance of MR_std_optional_std_string. Does nothing if the pointer is null.

MR_std_optional_std_string_DestroyArray()

MRC_API void MR_std_optional_std_string_DestroyArray

(

const MR_std_optional_std_string *

_this

)

Destroys a heap-allocated array of MR_std_optional_std_string. Does nothing if the pointer is null.

MR_std_optional_std_string_MutableValue()

MRC_API MR_std_string * MR_std_optional_std_string_MutableValue

(

MR_std_optional_std_string *

_this

)

The stored element or null if none, mutable. Parameter _this can not be null. It is a single object.

MR_std_optional_std_string_OffsetMutablePtr()

MRC_API MR_std_optional_std_string * MR_std_optional_std_string_OffsetMutablePtr	(	MR_std_optional_std_string *	ptr,
		ptrdiff_t	i )

Offsets a pointer to an array element by i positions (not bytes). Use only if you're certain that the pointer points to an array element.

MR_std_optional_std_string_OffsetPtr()

MRC_API const MR_std_optional_std_string * MR_std_optional_std_string_OffsetPtr	(	const MR_std_optional_std_string *	ptr,
		ptrdiff_t	i )

Offsets a pointer to an array element by i positions (not bytes). Use only if you're certain that the pointer points to an array element.

MR_std_optional_std_string_Value()

MRC_API const MR_std_string * MR_std_optional_std_string_Value

(

const MR_std_optional_std_string *

_this

)

The stored element or null if none, read-only. Parameter _this can not be null. It is a single object.
