Params

Params are modules that convert user provided input into rigid shapes used by middleware. Params have a 1:1 mapping to Smithy shapes.
Param modules will initialize Types and set members if they exist. Params will do lightweight validation (using Seahorse::Validator
) for aggregate structures, such as Array, Hash, and Set, so that values can be iterated over.
module SampleService
module Params
module HighScoreParams
def self.build(params, context: '')
Seahorse::Validator.validate!(params, Hash, Types::HighScoreParams, context: context)
type = Types::HighScoreParams.new
type.game = params[:game]
type.score = params[:score]
type
end
end
end
end
