json-iterator-lite
json-iterator is an alternative to encoding/json which does not use reflection.
This is a fork of the upstream project with everything that depends on reflection removed

Overview ¶
Package jsoniter implements encoding and decoding of JSON as defined in RFC 4627 and provides interfaces with identical syntax of standard lib encoding/json. Converting from encoding/json to jsoniter is no more than replacing the package with jsoniter and variable type declarations (if any). jsoniter interfaces gives 100% compatibility with code using standard lib.
"JSON and Go" (https://golang.org/doc/articles/json_and_go.html) gives a description of how Marshal/Unmarshal operate between arbitrary or predefined json objects and bytes, and it applies to jsoniter.Marshal/Unmarshal as well.
Besides, jsoniter.Iterator provides a different set of interfaces iterating given bytes/string/reader and yielding parsed elements one by one. This set of interfaces reads input as required and gives better performance.

Types ¶
type Iterator ¶
type Iterator struct {
Error error
Attachment interface{} // open for customized decoder
// contains filtered or unexported fields
}
Iterator is a io.Reader like object, with JSON specific read functions. Error is not returned as return value, but stored as Error member on this iterator instance.
func ParseBytes ¶
ParseBytes creates an Iterator instance from byte array
func ParseString ¶
ParseString creates an Iterator instance from string
func (*Iterator) CurrentBuffer ¶
CurrentBuffer gets current buffer as string for debugging purpose
func (*Iterator) ReadArray ¶
ReadArray read array element, tells if the array has more element to read.
func (*Iterator) ReadArrayCB ¶
ReadArrayCB read array with callback
func (*Iterator) ReadBigFloat ¶
ReadBigFloat read big.Float
func (*Iterator) ReadBigInt ¶
ReadBigInt read big.Int
func (*Iterator) ReadFloat32 ¶
ReadFloat32 read float32
func (*Iterator) ReadFloat64 ¶
ReadFloat64 read float64
func (*Iterator) ReadNumber ¶
ReadNumber read json.Number
func (*Iterator) ReadObject ¶
ReadObject read one field from object. If object ended, returns empty string. Otherwise, returns the field name.
func (*Iterator) ReadObjectCB ¶
ReadObjectCB read object with callback, the key is ascii only and field name not copied
func (*Iterator) ReadString ¶
ReadString read string from iterator
func (*Iterator) ReadStringAsSlice ¶
ReadStringAsSlice read string from iterator without copying into string form. The []byte can not be kept, as it will change after next iterator call.
func (*Iterator) ReadUint16 ¶
ReadUint16 read uint16
func (*Iterator) ReadUint32 ¶
ReadUint32 read uint32
func (*Iterator) ReportError ¶
ReportError record a error in iterator instance with current position.
func (*Iterator) ResetBytes ¶
ResetBytes reuse iterator instance by specifying another byte array as input
func (*Iterator) Skip ¶
func (iter *Iterator) Skip()
Skip skips a json object and positions to relatively the next json object
func (*Iterator) SkipAndAppendBytes ¶
SkipAndAppendBytes skips next JSON element and appends its content to buffer, returning the result.
func (*Iterator) SkipAndReturnBytes ¶
SkipAndReturnBytes skip next JSON element, and return its content as []byte. The []byte can be kept, it is a copy of data.
func (*Iterator) WhatIsNext ¶
WhatIsNext gets ValueType of relatively next json element
type Stream ¶
type Stream struct {
Error error
Attachment interface{} // open for customized encoder
// contains filtered or unexported fields
}
stream is a io.Writer like object, with JSON specific write functions. Error is not returned as return value, but stored as Error member on this stream instance.
