Types

type PaginationData

type PaginationData struct {
	Total        int64   // total record
	Page         int64   // current page
	PageSize     int64   // show size every page
	PageNums     int64   // show digital numbers on page
	FirstPage    int64   // first page
	LastPage     int64   // last page
	PreviousPage int64   // previous page
	NextPage     int64   // next page
	TotalPage    int64   // total page
	Pages        []int64 // pages
}

PaginationData pagination data

func Pagination

func Pagination(total, page, pageSize int64, pageNum int64) (pg *PaginationData)

Pagination calculate total record page current page pageSize show size every page pagesNum show digital numbers on page

type TSMap

type TSMap[K, T any] struct {
	// contains filtered or unexported fields
}

TSMap thread safe map

func (*TSMap[K, T]) Len

func (m *TSMap[K, T]) Len() int64

func (*TSMap[K, T]) Load

func (m *TSMap[K, T]) Load(key K) (T, bool)

Load returns the value stored in the map for a key, or nil if no value is present. The ok result indicates whether value was found in the map.

func (*TSMap[K, T]) LoadAndDelete

func (m *TSMap[K, T]) LoadAndDelete(key K) (T, bool)

LoadAndDelete deletes the value for a key, returning the previous value if any. The loaded result reports whether the key was present.

func (*TSMap[K, T]) LoadOrStore

func (m *TSMap[K, T]) LoadOrStore(key K, value T) (T, bool)

LoadOrStore returns the existing value for the key if present. Otherwise, it stores and returns the given value. The loaded result is true if the value was loaded, false if stored.

func (*TSMap[K, T]) Range

func (m *TSMap[K, T]) Range(f func(key K, value T) bool)

Range calls f sequentially for each key and value present in the map. If f returns false, range stops the iteration.

Range does not necessarily correspond to any consistent snapshot of the Map's contents: no key will be visited more than once, but if the value for any key is stored or deleted concurrently (including by f), Range may reflect any mapping for that key from any point during the Range call. Range does not block other methods on the receiver; even f itself may call any method on m.

Range may be O(N) with the number of elements in the map even if f returns false after a constant number of calls.

func (*TSMap[K, T]) Store

func (m *TSMap[K, T]) Store(key K, value T)
