Overview

Package sliceidx provides SliceIdx as a building block for creating types that fulfill idx.Index.

Index

• type SliceIdx
  • func New(sliceLen int) SliceIdx
  • func (si *SliceIdx) NextIdx() (idx int, app bool)
  • func (si *SliceIdx) Recycle(idx int)
  • func (si *SliceIdx) SetSliceLen(newlen int)

Types

type SliceIdx

type SliceIdx struct {
	SliceLen int
	MaxIdx   int
	Recycled []int
}

SliceIdx holds the logic for the slice index.

func New

func New(sliceLen int) SliceIdx

New creates a SliceIdx and sets the sliceLen.

func (*SliceIdx) NextIdx

func (si *SliceIdx) NextIdx() (idx int, app bool)

NextIdx gets the next index for the slice and if it requires an append action.

func (*SliceIdx) Recycle

func (si *SliceIdx) Recycle(idx int)

Recycle appends the idx to Recycled.

func (*SliceIdx) SetSliceLen

func (si *SliceIdx) SetSliceLen(newlen int)

SetSliceLen will set the SliceLen to newlen if newlen > SliceLen.
