comms::option::def::SequenceSerLengthFieldPrefix< TField, TReadErrorStatus > Struct Template Reference

#include "comms/options.h"

Detailed Description

template<typename TField, comms::ErrorStatus TReadErrorStatus = comms::ErrorStatus::InvalidMsgData>
struct comms::option::def::SequenceSerLengthFieldPrefix< TField, TReadErrorStatus >

Option that modifies the default behaviour of collection fields to prepend the serialised data with number of bytes information.

Similar to SequenceSizeFieldPrefix, but instead of number of elements to follow, the prefix field contains number of bytes that will follow.

using MyFieldBase = comms::Field<comms::option::def::BigEndian>;
using MyField =
    comms::field::ArrayList<
        MyFieldBase,
        comms::field::Bundle<
            std::tuple<
                comms::field::IntValue<MyFieldBase, std::uint32_t>,
                comms::field::String<MyFieldBase>
            >
        >,
        comms::option::def::SequenceSerLengthFieldPrefix<
            comms::field::IntValue<MyFieldBase, std::uint16_t>
        >
    >;

Template Parameters

TField	Type of the field that represents serialisation length
TReadErrorStatus	Error status to return in case read operation fails when should not
