Overview

Client represents a wrapper for the GRPC stub that allows for resolution of boolean, string, number, and object values. The implementation follows the details specified in openfeature.dev/docs/specification/sections/providers

The Client provides the following methods and attributes:

  • metadata - Returns the associated provider metadata with the name

  • fetch_boolean_value(flag_key:, default_value:, evaluation_context: nil) manner; client.fetch_boolean(flag_key: 'boolean-flag', default_value: false)

  • fetch_integer_value(flag_key:, default_value:, evaluation_context: nil) manner; client.fetch_integer_value(flag_key: 'integer-flag', default_value: 2)

  • fetch_float_value(flag_key:, default_value:, evaluation_context: nil) manner; client.fetch_float_value(flag_key: 'float-flag', default_value: 2.0)

  • fetch_string_value(flag_key:, default_value:, evaluation_context: nil) manner; client.fetch_string_value(flag_key: 'string-flag', default_value: 'some-default-value')

  • fetch_object_value(flag_key:, default_value:, evaluation_context: nil) manner; client.fetch_object_value(flag_key: 'flag', default_value: { default_value: 'value'})
