# Functions
Accum accumulates the result of repeatedly applying a simple function to the elements of a slice.
Accumx is the extended form of [Accum].
Append is the same as Go's builtin append and is included for completeness.
BinarySearch searches for target in a sorted slice and returns the position where target is found, or the position where target would appear in the sort order; it also returns a bool saying whether the target is really found in the slice.
BinarySearchFunc works like [BinarySearch], but uses a custom comparison function.
Clip removes unused capacity from the slice, returning s[:len(s):len(s)].
Clone returns a copy of the slice.
Combinations produces an iterator over all n-length combinations of distinct elements from s.
CombinationsWithReplacement produces an iterator over all n-length combinations of possibly repeated elements from s.
Compact replaces consecutive runs of equal elements with a single copy.
CompactFunc is like [Compact] but uses an equality function to compare elements.
Compare compares the elements of s1 and s2, using [cmp.Compare] on each pair of elements.
CompareFunc is like [Compare] but uses a custom comparison function on each pair of elements.
Concat returns a new slice concatenating the passed in slices.
Contains reports whether v is present in s.
ContainsFunc reports whether at least one element e of s satisfies f(e).
Delete removes the elements s[i:j] from s, returning the modified slice.
DeleteFunc removes any elements from s for which del returns true, returning the modified slice.
Each runs a simple function on each item of a slice.
Eachx is the extended form of [Each].
Equal reports whether two slices are equal: the same length and all elements equal.
EqualFunc reports whether two slices are equal using an equality function on each pair of elements.
Filter calls a simple predicate for each element of a slice, returning a slice of those elements for which the predicate returned true.
Filterx is the extended form of [Filter].
Get gets the idx'th element of s.
Group partitions the elements of a slice into groups.
Groupx is the extended form of [Group].
Grow increases the slice's capacity, if necessary, to guarantee space for another n elements.
Index returns the index of the first occurrence of v in s, or -1 if not present.
IndexFunc returns the first index i satisfying f(s[i]), or -1 if none do.
Insert inserts the given values at the idx'th location in s and returns the result.
IsSorted reports whether x is sorted in ascending order.
IsSortedFunc reports whether x is sorted in ascending order, with cmp as the comparison function as defined by [SortFunc].
KeyedSort sorts the given slice according to the ordering of the given keys, whose items must map 1:1 with the slice.
Map runs a simple function on each item of a slice, accumulating results in a new slice.
Mapx is the extended form of [Map].
Max returns the maximal value in x.
MaxFunc returns the maximal value in x, using cmp to compare elements.
Min returns the minimal value in x.
MinFunc returns the minimal value in x, using cmp to compare elements.
NonNil converts a nil slice to a non-nil empty slice.
Permutations produces an iterator over all permutations of s.
Prefix returns s up to but not including position idx.
Put puts a given value into the idx'th location in s.
RemoveN removes n items from s beginning at position idx and returns the result.
RemoveTo removes items from s beginning at position from and ending before position to.
Replace replaces the elements s[i:j] by the given v, and returns the modified slice.
ReplaceN replaces the n values of s beginning at position idx with the given values.
ReplaceTo replaces the values of s beginning at from and ending before to with the given values.
Reverse reverses the elements of the slice in place.
Rotate rotates a slice in place by n places to the right.
SliceN returns n elements of s beginning at position idx.
SliceTo returns the elements of s beginning at position from and ending before position to.
Sort sorts a slice of any ordered type in ascending order.
SortFunc sorts the slice x in ascending order as determined by the cmp function.
SortStableFunc sorts the slice x while keeping the original order of equal elements, using cmp to compare elements in the same way as [SortFunc].
Suffix returns s excluding elements before position idx.
