[go-nuts] Newbie question about type-casts

I have written my first little piece of Go-code. However it took some time and code for me to divide a int64 by 4 and round down. How can the last two lines be rewritten? Regards Martin package main import ( "fmt" "bufio" "math" ) var cash int64 scanne

Re: [go-nuts] builtin function definitions

The linked spec is the the definitive language specification. I read it carefully a couple of time (cannot recommend it enough) and knew about type switches. The most common language implementation is go's default compiler gc. Which is the place to implement the language spec and type

Re: [go-nuts] builtin function definitions

This is a special kind of switch called a type switch. You can read more about it in the language specification where its part of the intrinsic go syntax. https://golang.org/ref/spec#Switch_statements Because it is a special language construct you need to look at the compiler. You probably

Re: [go-nuts] Busy synchronization wait seems to behave differently on 1.13 and 1.14

I am not certain but the reason probably is the change to go-routine preemption in 1.14. From https://golang.org/doc/go1.14#runtime … Goroutines are now asynchronously preemptible. As a result, loops without function calls no longer potentially deadlock the scheduler or significantly delay

Re: [go-nuts] Weird benchmark results for seemingly identical functions

Let me quickly point out that your logic is inverted in the second code snippet because you break on the condition. That is most likely the reason for the difference. I guess the second example exits on the first iteration. for pos := 0; true; pos++ { if pos < suffixLen && pos <

[go-nuts] Interface method return other interface?

I'm wondering If it is ok (or good Go code) if an interface method returns an other interface? Here an example: type Querier interface { Query() string } type Decoder interface { DecodeAndValidate() Querier } -- You received this message because you are subscribed to the Google Groups
