Struct TupleHeadLayout 

pub struct TupleHeadLayout {
    pub end: Size,
    pub align: Align,
    pub packed_align: Option<Align>,
}

Describes what is needed to define the layout of the sized head of a tuple (head.., tail).

Fields

end: Size

The offset where the head ends and tail starts. This is the end of the last sized field; it is not necessarily aligned to align.

align: Align

The alignment of the head. This is the maximal alignment of any sized field and capped to the packed alignment.

packed_align: Option<Align>

If this is Some(a) the alignment of the tail will be capped at this value. Must be None for sized tuples.

Implementations

impl TupleHeadLayout

pub fn tail_offset(self, tail_align: Align) -> Size

Where the tail starts, given the aligment of the tail type.

pub fn full_size_and_align( self, tail_size: Size, tail_align: Align, ) -> (Size, Align)

The size and alignment of the full tuple, including the tail. Given the size and alignment of the tail type.

pub fn head_size_and_align(self) -> (Size, Align)

Returns the size and alignment of the tuple when there is no tail.
