pub const ABI_VERSION: u32 = 2;Expand description
Version of this descriptor layout and of the SDK-owned wire shapes.
Bump on any change to Desc, HostVtable, Buf, the status codes,
or any serde type this crate sends across the boundary (InitCx,
Manifest, Call, CallOut); the lumen_script types - PluginEvent
among them - are covered by Desc::script_wire_version instead.
2: dropped Desc::paint_wire_version (no paint types cross the
boundary), widening reserved in its place.
