// Marshal returns the JSON encoding of v.
|
|
//
|
|
// It's like json.Marshal, but with some differences:
|
|
//
|
|
// - It's ~4-5x faster in most cases.
|
|
//
|
|
// - It also supports custom Marshaler interface (MarshalJSONTo(buf []byte) []byte)
|
|
// to allow further optimizations.
|
|
//
|
|
// - It leverages the strutils library.
|
|
//
|
|
// - It drops the need to implement Marshaler or json.Marshaler by supports extra field tags:
|
|
//
|
|
// `byte_size` to format the field to human readable size.
|
|
//
|
|
// `unix_time` to format the uint64 field to string date-time without specifying MarshalJSONTo.
|
|
//
|
|
// `use_marshaler` to force using the custom marshaler for primitive types declaration (e.g. `type Status int`).
|
|
//
|
|
// - It correct the behavior of *url.URL and time.Duration.
|
|
//
|
|
// - It does not support maps other than string-keyed maps.
