Struct FlatDataFacet 

pub struct FlatDataFacet {
    pub is_plain: bool,
    pub loan_alignment: Option<u8>,
    pub explicit_fixed_layout: bool,
}

FlatData information attached to a node. Spec §4.5.

is_plain is recorded rather than derived on the spot because a frontend may assert it — a vendor extension can declare a type plain — and because the derivation walks the whole reachable graph.

Fields

is_plain: bool

Whether the type is plain: fixed size, no indirection, loanable without serialisation.

loan_alignment: Option<u8>

Alignment the zero-copy loan path requires.

explicit_fixed_layout: bool

Whether the frontend asked for fixed-size layout explicitly rather than the property being inferred.
