pub static VARIABLES: &[(&str, &str)]Expand description
Every variable() this target’s .dbds declare, as EPICS name and
declared type — the two columns dbWriteVariableFP prints
(dbStaticLib.c:1136-1149), which is what dbDumpVariable reports.
Name order, which is also C’s: dbVariable appends in load order, but
the loaded .dbd is dbExpand output and that tool emits each
declaration family sorted (measured in an installed softIoc.dbd).
