type AsyncPool deprecated 

type AsyncPool struct {
	// contains filtered or unexported fields
}

A long live, bounded pool of goroutines.

Use miso.NewAsyncPool to create a new pool.

AsyncPool internally maintains a task queue with limited size and limited number of workers.

By default, if the task queue is full and all workers are busy, the caller of *AsyncPool.Go is blocked indefinitively until the task can be processed. You can use DropTaskWhenPoolFull or CallerRunTaskWhenPoolFull to change this behaviour.

Deprecated: since v0.3.7, migrate to util/async pkg instead.

func NewAsyncPool deprecated 

func NewAsyncPool(maxTasks int, maxWorkers int, opts ...asyncPoolOption) *AsyncPool

Create a bounded pool of goroutines.

The maxTasks determines the capacity of the task queues.

The maxWorkers determines the max number of workers.

By default, if the task queue is full and all workers are busy, the caller of *AsyncPool.Go is blocked indefinitively until the task can be processed. You can use DropTaskWhenPoolFull or CallerRunTaskWhenPoolFull to change this behaviour.

Deprecated: since v0.3.7, migrate to util/async pkg instead.

func (p *AsyncPool) StopAndWait()

Stop the pool and wait until existing workers drain all the remaining tasks.

Once the pool is stopped, new tasks submitted are executed directly by the caller.

type Time added in v0.3.1 

type Time struct {
	time.Time
}

Enhanced wrapper of time.Time.

This type implements sql.Scanner and driver.Valuer, it can be safely used in GORM just like time.Time.

It also implements json/encoding Marshaler and Unmarshaler to support json marshalling.

In previous releases, Time was a type alias to time.Time. Since v0.1.2, Time embeds time.Time to access all of it's methods.

To cast from time.Time to Time, use WrapTime method. To cast from Time to time.Time, use Time.Unwrap method.

By default, Time support following unmarshaling formats:

  • time.RFC3339
  • time.RFC3339Nano
  • 2006-01-02 15:04:05.999999
  • 2006-01-02
  • 2006-01-02T15:04:05.999999
  • millseconds since unix epoch
  • seconds since unix epoch

By default, Time is marshaled as millseconds since unix epoch. You can change this behaviour though SetETimeMarshalFormat.
