Functions

func IsDigit

func IsDigit(r byte) bool

func Lcm

func Lcm(vals []uint32) uint32

Lcm returns the least common multiple

func Max

func Max(a, b uint32) uint32

func MaxInt

func MaxInt(a, b int) int

func Min

func Min(a, b uint32) uint32

func NaturalLess

Types

type BufferPool

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

func NewBufferPool

func NewBufferPool() *BufferPool

func (*BufferPool) Get

func (b *BufferPool) Get() []byte

func (*BufferPool) Put

func (b *BufferPool) Put(buf []byte)

type Limiter

type Limiter chan struct{}

Limiter provides a mechanism for limiting concurrency. Users need to call Acquire() before starting work and Release() when the work is done. Acquire() will block if the Limiters limit has already been reached and unblock when another thread calls Release(), or the passed context is canceled.

func NewLimiter

func NewLimiter(l int) Limiter

NewLimiter creates a limiter with l slots

func (Limiter) Acquire

func (l Limiter) Acquire(ctx context.Context) bool

Acquire returns when a slot is available. If the limit is reached it will block until another thread calls Release() or the context is done. In the latter case we return false.

func (Limiter) Release

func (l Limiter) Release()

type NaturalSortStringSlice

type NaturalSortStringSlice []string

NaturalSortStringSlice sorts strings lexicographically *except* substrings of numbers are sorted numerically

func (NaturalSortStringSlice) Len

func (ss NaturalSortStringSlice) Len() int

func (NaturalSortStringSlice) Less

func (ss NaturalSortStringSlice) Less(i, j int) bool

func (NaturalSortStringSlice) Swap

func (ss NaturalSortStringSlice) Swap(i, j int)
