Struct packet::records::RecordSequenceBuilder

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

A builder capable of serializing a sequence of records.

A RecordSequenceBuilder is instantiated with an Iterator that provides RecordBuilders to be serialized. The item produced by the iterator can be any type which implements Borrow<R> for R: RecordBuilder.

RecordSequenceBuilder implements InnerPacketBuilder.

Implementations

impl<R, I> RecordSequenceBuilder<R, I>

pub fn new(records: I) -> Self

Creates a new RecordSequenceBuilder with the given records.

records must produce the same sequence of values from every iteration, even if cloned. Serialization is typically performed with two passes on records: one to calculate the total length in bytes (serialized_len) and another one to serialize to a buffer (serialize_into). Violating this rule may result in panics or malformed serialized record sequences.

impl<R, I> RecordSequenceBuilder<R, I>where R: RecordBuilder, I: Iterator + Clone, I::Item: Borrow<R>,

pub fn serialized_len(&self) -> usize

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

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.
