Struct DbNode 

pub struct DbNode {
    pub name: String,
    pub alias_of: Option<String>,
}

One node of the list C’s dbFirstRecord / dbNextRecord pair walks.

C keeps records and aliases in a single per-record-type recList: dbCreateAlias ellAdds the alias node into the very list the records live in (dbStaticLib.c:1703). A walk that wants records only therefore has to SAY so — if (dbIsAlias(pdbentry)) continue, as dbjlr (dbJLink.c:520) and dbcar (dbCaTest.c:85) do — and a walk that says nothing lists both, as dbl (dbTest.c:180-185) and dbglob (:325-333) do.

This port holds the two in separate maps, so “record or alias” was a question each caller answered for itself, and every caller that answered it by walking all_record_names alone answered it wrong for aliases with no way to notice. PvDatabase::all_db_nodes reassembles C’s one list; alias_of is dbIsAlias.

Fields

name: String

The name this node is reached by — an alias node carries the ALIAS name, which is what C prints from dbGetRecordName.

alias_of: Option<String>

The record an alias node stands for, or None for a record node.
