pub const MANIFEST_MAP_TABLES: &[(&str, &[&str])];Expand description
#2207 (packaging slice 1): the map tables, each with the keys one of
its entries accepts. A map table’s own keys are names the user chooses
(dependency aliases, registry names), checked against decision G’s grammar;
each entry is a table of fixed keys, refused with did-you-mean like
MANIFEST_TABLES’ keys are.
