What did you do?
//go:build wireinject
// +build wireinject
package main
import (
"io"
"os"
"github.com/google/wire"
)
type foo struct{}
type bar struct{}
func (foo) injectWriter() io.Writer {
wire.Build(wire.InterfaceValue(new(io.Writer), os.Stdout))
return nil
}
func (bar) injectWriter() io.Writer {
wire.Build(wire.InterfaceValue(new(io.Writer), os.Stderr))
return nil
}
What did you expect to see?
package main
import (
"io"
"os"
)
// Injectors from main.go:
func (foo) injectWriter() io.Writer {
writer := _wireFileValue
return writer
}
var (
_wireFileValue = os.Stdout
)
func (bar) injectWriter() io.Writer {
writer := _wireOsFileValue
return writer
}
var (
_wireOsFileValue = os.Stderr
)
// main.go:
type foo struct{}
type bar struct{}
What did you see instead?
Wire generates broken code. It generates function without receiver.
package main
import (
"io"
"os"
)
// Injectors from main.go:
func injectWriter() io.Writer {
writer := _wireFileValue
return writer
}
var (
_wireFileValue = os.Stdout
)
func injectWriter() io.Writer {
writer := _wireOsFileValue
return writer
}
var (
_wireOsFileValue = os.Stderr
)
// main.go:
type foo struct{}
type bar struct{}
