Overview ¶
Package fastjson provides a code generator and library for fast JSON encoding, limited to what apm-agent-go requires.
fastjson reuses a small amount of easyjson's code for marshalling strings. Whereas easyjson relies on pooled memory, fastjson leaves memory allocation to the user. For apm-agent-go, we always encode from a single goroutine, so we can reuse a single buffer, and so we can almost always avoid allocations.

Types ¶
type Appender ¶
type Appender interface {
// AppendJSON appends the JSON representation of the value to the
// buffer, and returns the extended buffer.
AppendJSON([]byte) []byte
}
Appender defines an interface that types can implement to append their JSON representation to a buffer. If the value is not a valid JSON token, it will be rejected.
type Marshaler ¶
type Marshaler interface {
// MarshalFastJSON writes a JSON representation of the type to w.
MarshalFastJSON(w *Writer)
}
Marshaler defines an interface that types can implement to provide fast JSON marshaling.
type Writer ¶
type Writer struct {
// contains filtered or unexported fields
}
Writer is a JSON writer.
func (*Writer) Bytes ¶
Bytes returns the internal buffer. The result is invalidated when Reset is called.
func (*Writer) Rewind ¶
Rewind rewinds the buffer such that it has size bytes, dropping everything proceeding.
func (*Writer) StringContents ¶
StringContents is the same as String, but without the surrounding quotes.
