Enum ArrayElementFlattening 

pub enum ArrayElementFlattening {
    ThroughAliasesAndArrays,
    StopsAtAlias,
}

Whether an array’s element is flattened through aliases and inner arrays before the delimiter question (crate::array_is_delimited).

XTypes models a multi-dimensional array as one ARRAY_TYPE over the base element, so the specification’s reading — and Cyclone DDS’s and Fast DDS’s, both measured byte-identical on resolve-array-of-typedef-array — sees typedef long Row[3]; Row grid[2]; as an array of long and writes no DHEADER. OpenDDS stops at the alias: its generated serialiser treats the Row element as a constructed type and writes the inner DHEADER — measured 2026-08-24, 32 octets against 28 for the same values under XCDR2. Orthogonal to CollectionDelimiterPolicy: OpenDDS and Cyclone share Specification there and part here.

Variants

ThroughAliasesAndArrays

Through aliases and inner arrays to the base element — the specification’s reading.

StopsAtAlias

The element is taken as declared: an alias of an array is a constructed type and the array is delimited. OpenDDS.

Implementations

impl ArrayElementFlattening

pub const ALL: [Self; 2]

Both readings.

pub const fn is_default(self) -> bool

Whether this is the default.

pub const fn as_str(self) -> &'static str

Short name, for configuration and diagnostics.

pub fn parse(text: &str) -> Option<Self>

The named reading, or None for anything else.
