    14  // This conditionally-compiled file provides custom marshal/unmarshal functions for our top-level
    15  // data model types in EasyJSON.
    16  //
    17  // EasyJSON's code generator does recognize the same MarshalJSON and UnmarshalJSON methods used by
    18  // encoding/json, and will call them if present. But this mechanism is inefficient: when marshaling
    19  // it requires the allocation of intermediate byte slices, and when unmarshaling it causes the
    20  // JSON object to be parsed twice. It is preferable to have our marshal/unmarshal methods write to
    21  // and read from the EasyJSON Writer/Lexer directly. Our go-jsonstream library provides methods for
    22  // doing this, if the launchdarkly_easyjson build tag is set.package ldmodel
    23  //
