type BlackHole ¶
type BlackHole struct{}
A BlackHole is an io.ReadWriteCloser that accepts an infinite amount of input and produces no output.
type RefCount ¶
type RefCount struct {
// contains filtered or unexported fields
}
A Refcount can be embedded in structures to provide reference-counting of resources.
Example ¶
package main
import "aqwari.net/net/styx/internal/util"
type Session struct {
util.RefCount
User, Tree string
Requests chan []byte
}
func (s *Session) end() {
select {
case <-s.Requests:
return
}
}
func main() {
s := &Session{Requests: make(chan []byte)}
for i := 0; i < 10; i++ {
s.IncRef()
}
for i := 0; i < 20; i++ {
if !s.DecRef() {
s.end()
break
}
}
}
Output:
type SectionWriter ¶
type SectionWriter struct {
// contains filtered or unexported fields
}
Section writer provides a partial analogue io.SectionReader, for writers.
func NewSectionWriter ¶
func NewSectionWriter(w io.WriterAt, off, n int64) *SectionWriter
