Types

type Dict

type Dict[K constraints.Ordered, V any] interface {
	GetSetter[K, V]
	KVLister[K, V]
}

type GetSetter

type GetSetter[K constraints.Ordered, V any] interface {
	Get(key K) (value V, ok bool)
	Set(key K, value V) error
}

type GlobalVar

type GlobalVar[T any] struct {
	// contains filtered or unexported fields
}

func (*GlobalVar[T]) Get

func (v *GlobalVar[T]) Get() T

func (*GlobalVar[T]) Set

func (v *GlobalVar[T]) Set(t T)

func (*GlobalVar[T]) String

func (v *GlobalVar[T]) String() string

type KVLister

type KVLister[K constraints.Ordered, V any] interface {
	Keys() []K
	Values() []V
}

type Slc

type Slc[T any] []T // sorted in alphabetical order ...

func CheckSize

func CheckSize[T any](plist *Slc[T]) *Slc[T]

CheckSize accepts a pointer to a slice and checks to see if the len of a slice is within 20% of the capacity of the slice and reallocates if necessary.

If the capacity is still sufficient, it returns the initial pointer unchanged.

If the capacity is insufficient, it allocates a new slice, sets the old slice equal to the new slice, and returns a pointer to the new slice.

The default 20% warning and 200% allocation can be overridden by setting the config variables DefaultSliceCheck and DefaultSliceAlloc, respectively.

func NewList

func NewList[T any](n int) Slc[T]

func (*Slc[T]) Append

func (l *Slc[T]) Append(v T)

func (Slc[T]) Len

func (l Slc[T]) Len() int

func (Slc[T]) Less

func (l Slc[T]) Less(i, j int) bool

func (Slc[T]) Swap

func (l Slc[T]) Swap(i, j int)
