Instance Method Detail

def alignment(*args, **options) #

See StructLayout.


def alignment(*args, **options, &) #

See StructLayout.


def from?(form : StructViewForm) #

def make! : StructView #

Constructs a struct view for this struct type.

This method is unsafe: the resulting struct view's content is unmoderated. You'll need to fill all fields with values before the struct view could be considered well-defined.


def padded_size(*args, **options) #

See StructLayout.


def padded_size(*args, **options, &) #

See StructLayout.


def references?(*args, **options) #

See StructLayout.


def references?(*args, **options, &) #

See StructLayout.


def to_s(io) #

abstract def view_for(handle : Pointer(Void)) : StructView #

Returns the struct view corresponding to this struct type, wrapped around the given handle.
