module RemiLib::RSConf::HashValueConverter(Converter)

Overview

Converter to be used with RemiLib::RSConf::Serializable to serialize the values of a Hash(String, V) with the custom converter.

require "libremiliacr"
alias RSConf = RemiLib::RSConf

class TimestampHash
  include RSConf::Serializable

  @[RSConf::Field(converter: RSConf::HashValueConverter(Time::EpochConverter))]
  property birthdays : Hash(String, Time)
end

timestamp = TimestampHash.fromRsconf(%|{"birthdays":{"foo":1459859781,"bar":1567628762}}|)
puts timestamp.birthdays # => {"foo" => 2016-04-05 12:36:21 UTC, "bar" => 2019-09-04 20:26:02 UTC}
puts timestamp.toRsconf

RemiLib::RSConf::HashValueConverter.new should be used if the nested converter is also an instance instead of a type.

require "libremiliacr"
alias RSConf = RemiLib::RSConf

class TimestampHash
  include RSConf::Serializable

  @[RSConf::Field(converter: RSConf::HashValueConverter.new(Time::Format.new("%b %-d, %Y")))]
  property birthdays : Hash(String, Time)
end

timestamp = TimestampHash.fromRsconf(%|{"birthdays":{"foo":"Apr 5, 2016","bar":"Sep 4, 2019"}}|)
puts timestamp.birthdays # => {"foo" => 2016-04-05 00:00:00 UTC, "bar" => 2019-09-04 00:00:00 UTC}
puts timestamp.toRsconf

This implies that RemiLib::RSConf::HashValueConverter(T) and RemiLib::RSConf::HashValueConverter(T.class).new(T) perform the same serializations.
