# rescue
Aggregate errors/panics from goroutines
## Auto-capture panics (single goroutine)
```go
func Foo(ctx context.Context) {
defer rescue.Do(ctx)
...
}
r := rescue.New()
go Foo(r.Context(ctx))
r.Wait()
if err := r.Error(ctx); err != nil {
... handle panic ...
}
```
## Auto-capture errors (single goroutine)
```go
func Foo(ctx context.Context) (err error){
rescue.Bind(ctx, &err)
defer rescue.Do(ctx)
...
}
r := rescue.New()
go Foo(r.Context(ctx))
r.Wait()
if err := r.Error(ctx); err != nil {
// Because this shares the interface panics,
// we need to convert types
switch err := err.(type) {
case error:
... handle error ...
default:
... handle panic ...
}
}
```
## Capture errors and panics within multiple goroutines
```go
func Foo(ctx context.Context) (err error){
rescue.Bind(ctx, &err)
defer rescue.Do(ctx)
...
}
rg := rescue.NewGroup()
for i := 0; i < 10; i++ {
r := rg.New()
go Foo(r.Context(ctx))
}
rg.Wait()
for err := rage rg.Errors() {
// Because this shares the interface panics,
// we need to convert types
switch err := err.(type) {
case error:
... handle error ...
default:
... handle panic ...
}
}
