Struct AlignedRecordSequenceBuilder 

pub struct AlignedRecordSequenceBuilder<R, I> { /* private fields */ }

A builder capable of serializing a sequence of aligned records.

An AlignedRecordSequenceBuilder is instantiated with an Iterator that provides AlignedRecordBuilders to be serialized. The item produced by the iterator can be any type which implements Borrow<R> for R: AlignedRecordBuilder.

AlignedRecordSequenceBuilder implements InnerPacketBuilder.

Implementations

impl<R, I> AlignedRecordSequenceBuilder<R, I>

pub fn new(start_pos: usize, records: I) -> Self

Creates a new AlignedRecordSequenceBuilder with given records and start_pos.

records must produce the same sequence of values from every iteration, even if cloned. See RecordSequenceBuilder for more details.

Alignment is calculated relative to the beginning of a virtual space of bytes. If non-zero, start_pos instructs the serializer to consider the buffer passed to serialize_into to start at the byte start_pos within this virtual space, and to calculate alignment and padding accordingly. For example, in the IPv6 Hop-by-Hop extension header, a fixed header of two bytes precedes that extension header’s options, but alignment is calculated relative to the beginning of the extension header, not relative to the beginning of the options. Thus, when constructing an AlignedRecordSequenceBuilder to serialize those options, start_pos would be 2.

impl<R, I> AlignedRecordSequenceBuilder<R, I>

where R: AlignedRecordBuilder, I: Iterator + Clone, I::Item: Borrow<R>,

pub fn serialized_len(&self) -> usize

Returns the total length, in bytes, of the serialized records contained within self.

Note that this length includes all padding required to ensure that all records satisfy their alignment requirements.

pub fn serialize_into(&self, buffer: &mut [u8])

Serializes all the records contained within self into the given buffer.

Panics

serialize_into expects that buffer has enough bytes to serialize the contained records (as obtained from serialized_len), otherwise it’s considered a violation of the API contract and the call may panic.
