Use buffered channel to implement thread-safe Pool_golang in the Go language

Overview

We already know that the Go language provides sync. Pool, but not very well done, so it is necessary to implement a pool of their own.

Let me see the code:

Copy Code code as follows:

Type Pool struct {
Pool Chan *client
}

Create a new pool
Func newpool (max int) *pool {
Return &pool{
Pool:make (Chan *client, Max),
}
}

Borrow a Client from pool.
Func (P *pool) borrow () *client {
var cl *client
Select {
Case CL = <-p.pool:
Default
CL = Newclient ()
}
return CL
}

And go back.
Func (P *pool) return (CL *client) {
Select {
Case P.pool <-CL:
Default
Let it go, let it go ...
}
}

Summarize

Do not use sync now. Pool
