Types ¶
type ContextReader ¶
type ContextReader interface {
// Read behaves like a blocking io.Reader.Read.
//
// Read wraps ReadContext with a background context.
Read(b []byte) (n int, err error)
// ReadContext is an io.Reader that blocks until data is available or
// until ctx is done.
ReadContext(ctx context.Context, b []byte) (n int, err error)
}
ContextReader is a cancelable io.Reader.
func DefaultReaderWithContext ¶
func DefaultReaderWithContext(ctx context.Context) ContextReader
DefaultReaderWithContext returns a context-aware io.Reader.
Because this stores the context, only use this in situations where an io.Reader is unavoidable.
