class DatabaseConfigurations
# A HashConfig object is created for each database configuration entry that
# is created from a hash.
#
# A hash config:
#
# { "development" => { "database" => "db_name" } }
#
# Becomes:
#
# #<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbded10
# @env_name="development", @spec_name="primary", @config={"database"=>"db_name"}>
#
# ==== Options
#
# * <tt>:env_name</tt> - The Rails environment, i.e. "development".
# * <tt>:spec_name</tt> - The specification name. In a standard two-tier
# database configuration this will default to "primary". In a multiple
# database three-tier database configuration this corresponds to the name
# used in the second tier, for example "primary_readonly".
# * <tt>:config</tt> - The config hash. This is the hash that contains the
# database adapter, name, and other important information for database
# connections.
