Types

type CmdTry

type CmdTry struct {
	Args []string
	Ran  *bool
}

type MutexIf

type MutexIf struct {
	sync.Mutex
}

A `sync.Mutex` wrapper for convenient conditional `defer`d un/locking.

Example: `defer mut.UnlockIf(mut.LockIf(mycondition))`

func (*MutexIf) Lock

func (me *MutexIf) Lock() bool

func (*MutexIf) LockIf

func (me *MutexIf) LockIf(lock bool) bool

Calls `me.Lock` if `lock` is `true`, then returns `lock`.

func (*MutexIf) UnlockIf

func (me *MutexIf) UnlockIf(unlock bool)

Calls `me.Unlock` if `unlock` is `true`.
