Enum PayloadLayout 

pub enum PayloadLayout {
    Empty,
    Fixed,
    VersionSelected,
    VersionAndLengthSelected,
    MinimumLengthPreserved,
    LengthPrefixed,
    BoundedPreserved,
    BoundedOpaque,
    DynamicWordPadded,
    Opaque,
}

The rule used to choose and bound a message payload layout.

Variants

Empty

No semantic payload bytes are carried.

Fixed

One fixed layout is used for all supported protocol versions.

VersionSelected

The negotiated protocol selects between fixed layouts.

VersionAndLengthSelected

The negotiated protocol and exact body length jointly select a layout.

MinimumLengthPreserved

A typed fixed prefix is decoded while a bounded extension is preserved.

LengthPrefixed

A bounded length/count field controls a variable tail.

BoundedPreserved

A bounded payload is retained exactly while consumers may inspect it.

BoundedOpaque

A bounded extension is retained byte-for-byte because its internal schema is not modeled.

DynamicWordPadded

NUL-terminated station strings are followed by zero bytes to a four-byte boundary.

Opaque

The crate deliberately does not interpret the payload.
