Enum WstringUnitWidth 

pub enum WstringUnitWidth {
    Two,
    Four,
}

C3 — how wide one UTF-16 code unit is on the wire.

The transmission code set’s width. No GIOP version fixes it and XTypes Table 31 fixes it at two, so it varies independently of C1 and C2 — which is why these are three types and not one enumeration of named forms.

Not WcharWidth, and the difference is measured: rmw_cyclonedds_cpp 1.3.4 writes a two-octet scalar wchar and four-octet wstring code units, so the scalar’s width is its own axis. See zerodds_ast_layout::WcharWidth.

Variants

Two

Two octets. XTypes Table 31, Cyclone, OpenDDS, Fast DDS, omniORB, JacORB.

Four

Four octets, a code unit zero-extended — not a code point, so U+1D11E stays the surrogate pair 34d80000 1edd0000. RTI under XCDR1, TAO, and both ROS type supports.
