source§fn decode(&mut self, decoder: &mut Decoder<'_>, offset: usize) -> Result<()>
fn decode(&mut self, decoder: &mut Decoder<'_>, offset: usize) -> Result<()>
Decodes an object of this type from the decoder’s buffers into
self
.
Callers must ensure that offset
is a multiple of
Layout::inline_align
, and that decoder.buf
has room for reading
Layout::inline_size
bytes at offset

fn encode( &mut self, encoder: &mut Encoder<'_, '_>, offset: usize, recursion_depth: usize ) -> Result<()>
Encode the object into the buffer. Any handles stored in the object are
swapped for
Handle::INVALID
. Callers must ensure that offset
is a
multiple of Layout::inline_align

source§fn inline_align(_context: &Context) -> usize
fn inline_align(_context: &Context) -> usize
Returns the minimum required alignment of the inline portion of the
encoded object. It must be a (nonzero) power of two.
source§fn inline_size(context: &Context) -> usize
fn inline_size(context: &Context) -> usize
Returns the size of the inline portion of the encoded object, including
padding for the type’s alignment. Must be a multiple of
inline_align
