YAML::DBM#index

index( keystr )

# File tmp/rubies/ruby-3.2.0/lib/yaml/dbm.rb, line 76
def index( keystr )
    super( keystr.to_yaml )
end

Deprecated, used YAML::DBM#key instead.

Note: YAML::DBM#index makes warning from internal of ::DBM#index. It says ‘DBM#index is deprecated; use DBM#key’, but DBM#key behaves not same as DBM#index.
