Enum OutboundField 

pub enum OutboundField {
    Raw {
        tag: u32,
        value: Vec<u8>,
    },
    Data {
        length_tag: u32,
        data_tag: u32,
        value: Vec<u8>,
    },
}

A single body field of an OutboundMessage, in the form the encoder needs to stamp it.

Most fields are OutboundField::Raw and are written verbatim. A FIX DATA field (RawData/96, Signature/89, the Encoded* family) legally contains the SOH delimiter and =, so it is decodable only alongside its paired LENGTH field; those fields are OutboundField::Data and are emitted as a counted pair so the payload’s SOH bytes are never read as field terminators.

Variants

Raw

An ordinary field, written as tag=value<SOH>.

Fields

tag: u32

The field tag number.

value: Vec<u8>

The field value bytes.

Data

A counted LENGTH/DATA pair, written as length_tag=<value.len()><SOH>data_tag=<value><SOH>.

Fields

length_tag: u32

The LENGTH field tag (e.g., 95 RawDataLength).

data_tag: u32

The paired DATA field tag (e.g., 96 RawData).

value: Vec<u8>

The raw payload, which may carry SOH and =.
