containedctx is a linter that detects struct contained context.Context field. This is discouraged technique in favour of passing context as first argument of method or function. For rationale please read Contexts and structs the Go blog post.
go install github.com/sivchari/containedctx/cmd/containedctx
package main
import "context"
type ok struct {
i int
s string
}
type ng struct {
ctx context.Context
}
type empty struct{}
go vet -vettool=(which containedctx) ./...
