Functions

func CopyMap

func CopyMap[K comparable, V any](m map[K]V) map[K]V

CopyMap allows to return a copy of the map provided. NOTE: it is NOT a deep copy, but just simply produces the copy of the map

func GetFirst

func GetFirst[K comparable, V any](m map[K]V) (K, V, bool)

GetFirst returns the first (pretty random) element in the map m. This weird function maybe helpful if we know that the len(m) == 1 and we need just get the elements out of there

func IndexOf

func IndexOf[V comparable](slice []V, v V) int

IndexOf returns the position of v in slice and -1 if the v is not in slice.

func IndexOfAny

func IndexOfAny[V any](slice []V, v V, equalF func(v1, v2 V) bool) int

IndexOfAny returns the position of v in slice and -1 if the v is not in slice.

func Keys

func Keys[K comparable, V any](m map[K]V) []K

Keys returns keys list (slice is created) or nil

func MergeSlicesUnique

func MergeSlicesUnique[V comparable](slices ...[]V) []V

MergeSlicesUnique receives slices and form one with unique values from all of them

func NewRingBuffer

func NewRingBuffer[V any](size uint) *ringBuffer[V]

NewRingBuffer returns the new instance of the *ringBuffer (which implements the RingBuffer)

func SliceCopy

func SliceCopy[V any](v []V) []V

SliceCopy makes a copy of slice

func SliceExcludeOverlaps

func SliceExcludeOverlaps[V comparable](s1, s2 []V) ([]V, []V)

SliceExcludeOverlaps returns unique elements in each slice of two first return param(unique in s1) - present in s1, but not in s2 second return param(unique in s2) - present in s2, but not in s1,

func SliceExludeUniqueS2

func SliceExludeUniqueS2[V comparable](s1, s2 []V) ([]V, []V)

SliceExludeS2Unique substracts elements s2 from the s1 and returns the following: first param - elements that present in s1, but not in s2 second param - elements that present in s1 and s2 both

func SliceFill

func SliceFill[V any](s []V, v V)

SliceFill sets all values of s to v

func SliceRemoveIdx

func SliceRemoveIdx[V any](slice []V, idx int) []V

SliceRemoveIdx removes the element at idx from the slice and return the updated slice. the function does it in place, so the original slice is changed

func SliceReverse

func SliceReverse[V any](slice []V) []V

SliceReverse the slice in place and returns the slice itself

func Values

func Values[K comparable, V any](m map[K]V) []V

Values returns values list (slice is created) or nil

Types

type RingBuffer

type RingBuffer[V any] interface {
	// Write allows to write the value v into the buffer. It may return errors.ErrExhausted
	// if the maximum capacity of the buffer is reached
	Write(v V) error
	// Read reads the value from the buffer. It will return io.EOF if the buffer is empty
	Read() (V, error)
	// ReadN allows to read multiple values into the slice dst. It will return number of
	// values read
	ReadN(dst []V) int
	// Skip allows to skip first n values. It returns the actual number of values skipped
	Skip(n int) int
	// At returns the element at the index idx. It doesn't change the buffer values
	At(idx int) V
	// Clear removes all elements from the buffer
	Clear()
	// Len returns the actual number of values can be read
	Len() int
	// Cap returns the maximum buffer capacity
	Cap() int
}

RingBuffer is an interface for working with the FIFO buffer with the fixed size
