Functions ¶
func ClearFlag ¶
ClearFlag returns a new Context that no longer carries flag.
Example ¶
package main
import (
"context"
"fmt"
"github.com/vardius/go-api-boilerplate/pkg/executioncontext"
)
func main() {
ctx := context.Background()
ctx = executioncontext.WithFlag(ctx, executioncontext.LIVE)
ctx = executioncontext.WithFlag(ctx, executioncontext.REPLAY)
ctx = executioncontext.ClearFlag(ctx, executioncontext.LIVE)
fmt.Printf("%v\n", executioncontext.Has(ctx, executioncontext.LIVE))
fmt.Printf("%v\n", executioncontext.Has(ctx, executioncontext.REPLAY))
}
Output: false true
func Has ¶
has returns the bool value based on flag occurrence in context.
Example ¶
package main
import (
"context"
"fmt"
"github.com/vardius/go-api-boilerplate/pkg/executioncontext"
)
func main() {
ctx := context.Background()
fmt.Printf("%v\n", executioncontext.Has(ctx, executioncontext.LIVE))
ctx = executioncontext.WithFlag(ctx, executioncontext.LIVE)
fmt.Printf("%v\n", executioncontext.Has(ctx, executioncontext.LIVE))
}
Output: false true
func ToggleFlag ¶
ToggleFlag returns a new Context with toggled flag.
Example ¶
package main
import (
"context"
"fmt"
"github.com/vardius/go-api-boilerplate/pkg/executioncontext"
)
func main() {
ctx := context.Background()
ctx = executioncontext.WithFlag(ctx, executioncontext.LIVE)
ctx = executioncontext.ToggleFlag(ctx, executioncontext.REPLAY)
fmt.Printf("%v\n", executioncontext.Has(ctx, executioncontext.LIVE))
fmt.Printf("%v\n", executioncontext.Has(ctx, executioncontext.REPLAY))
}
Output: true true
func WithFlag ¶
WithFlag returns a new Context that carries flag.
Example ¶
package main
import (
"context"
"fmt"
"github.com/vardius/go-api-boilerplate/pkg/executioncontext"
)
func main() {
ctx := context.Background()
ctx = executioncontext.WithFlag(ctx, executioncontext.LIVE)
fmt.Printf("%v\n", executioncontext.Has(ctx, executioncontext.LIVE))
}
Output: true
Types ¶
type Flag ¶
type Flag uint8
Flag type
Execution context flags
func FromContext ¶
FromContext returns the slice of flags stored in ctx
Example ¶
package main
import (
"context"
"fmt"
"github.com/vardius/go-api-boilerplate/pkg/executioncontext"
)
func main() {
ctx := context.Background()
flags := executioncontext.FromContext(ctx)
fmt.Printf("%v\n", flags)
ctx = executioncontext.WithFlag(ctx, executioncontext.LIVE)
ctx = executioncontext.WithFlag(ctx, executioncontext.REPLAY)
flags = executioncontext.FromContext(ctx)
fmt.Printf("%v\n", flags)
}
Output: 0 3
