Proposal When writing code on a daily basis, for the methods of a struct, the first letter of the struct's name is often used to name the method receiver. However, this approach often leads to naming conflicts. For example: type Chat struct { db any } func (c *Chat) Func1() { fm...
Extend the concept of methods to include operations on structfield types. For example, allowing == to work with structfield to compare field values. Ensure that accessing non-existent fields results in compile-time errors or runtime panics, similar to how Go handles other errors. Orthogonality: ...

构建高效golang线程池 | 在 Golang 中实现线程池通常使用的是 goroutine 和 channel,可以通过 channel 控制 goroutine 的数量,从而实现线程池的功能。下面是一个简单的实现: package main import ( "fmt" "sync" ) type Task struct { TaskFunc func() error Done chan error } func NewTask(taskFunc func...
theError() stringmethod on one of theirstructerror types. Sometimes it can be tedious to create thesestructtypes if you have a number of errors that don’t need to be handled explicitly by the callers, though, so in Go 1.13, the language added features to make it easier to handle ...
// // If the deadline is exceeded a call to Read or Write or to other I/O // methods will return an error that wraps ErrDeadlineExceeded. // This can be tested using errors.Is(err, os.ErrDeadlineExceeded). // That error implements the Timeout method, and calling the Timeout /...
panic: runtime.AddCleanup: ptr is equal to arg, cleanup will never run What did you expect to see? I would expect that thissnippet of codeto be more robust to the case of struct embedding (if that is at all possible), or the documentation forruntime.AddFuncalso mention that naive str...

The difference between the GetAllIndexes and the GetAllRawIndexes method is that the first one returns a list of Index who is a struct use like a type and the second returns just a golang type []map[string]interface{}. Contributor Joel-Nickson commented on Oct 21, 2021 • edited Is...
