Functions ¶
func ApplyMapFunction ¶
func ApplyMapFunction[T1, T2 any](s []T2, f func(T2) T1) []T1
ApplyMapFunction applies the function to each element of the slice and returns a new slice of the results in the same order. Don't confuse with the data structure `map` More info at: https://en.wikipedia.org/wiki/Map_(higher-order_function)
func ApplyMapFunctionRemovingDuplicates ¶
func ApplyMapFunctionRemovingDuplicates[T1 comparable, T2 any](s []T2, f func(T2) T1) []T1
ApplyMapFunctionRemovingDuplicates applies the function to each element of the slice and returns a new slice of the results in the same order, but without duplicates.
func ApplyReduceFunction ¶
func ApplyReduceFunction[T1, T2 any](s []T1, f func(T1, T2) T2, initVal T2) T2
ApplyReduceFunction applies a function to each element of the slice and returns a single value. It can also be called a `Fold`. This specific implementation is equivalent to a foldl More info at: https://en.wikipedia.org/wiki/Fold_(higher-order_function)
func GroupBy ¶
func GroupBy[T1 any, T2 comparable](slice []T1, projection func(T1) T2) map[T2][]T1
GroupBy groups the elements of the slice into a new map, where the keys are the result of the projection and the values are the elements of the slice with that projection. WARNING: don't assume any order in the slices of the values of the map. The original order is not preserved.
func GroupByUniqueProjection ¶
func GroupByUniqueProjection[T1 any, T2 comparable](slice []T1, projection func(T1) T2) (map[T2]T1, error)
GroupByUniqueProjection groups the elements of the slice by the result of the given function. If two elements have the same projection, it returns an error.
func GroupByWithJoinFunction ¶
func GroupByWithJoinFunction[TOrig any, TKey comparable, TValue any](slice []TOrig, projection func(TOrig) TKey, join func(TOrig, TValue) TValue) map[TKey]TValue
GroupByWithJoinFunction groups the elements of the slice by the result of the given "projection" function and joins the result with the previous elements in that group using the "join" function" WARNING: don't assume any order in the join function. The original order is not guaranteed
func HasDuplicateField ¶
func HasDuplicateField[T1 any, T2 comparable](elems []T1, projector func(T1) T2) bool
HasDuplicateField returns true if the slice has at least two elements with the same value when projected by the given function.
func IsOneOf ¶
func IsOneOf[T comparable](s []T, elem T) bool
IsOneOf returns true iff the element is in the slice.
func RemoveDuplicates ¶
func RemoveDuplicates[T1 comparable](s []T1) []T1
RemoveDuplicates returns a new slice with the same elements as the input slice, but without duplicates.
