module String::RawConverter
¶
Converter to be used with JSON::Serializable
to read the raw
value of a JSON object property as a String
.
It can be useful to read ints and floats without losing precision, or to read an object and deserialize it later based on some condition.
require "json"
class Raw
include JSON::Serializable
@[JSON::Field(converter: String::RawConverter)]
property value : String
end
raw = Raw.from_json(%({"value": 123456789876543212345678987654321}))
raw.value # => "123456789876543212345678987654321"
raw.to_json # => %({"value":123456789876543212345678987654321})
