Functions ¶
func Clip ¶
func Clip[S ~[]E, E any](s S) S
Clip removes unused capacity from the slice, returning s[:len(s):len(s)].
func Clone ¶
func Clone[S ~[]E, E any](s S) S
Clone returns a copy of the slice. The elements are copied using assignment, so this is a shallow clone.
func Compact ¶
func Compact[S ~[]E, E comparable](s S) S
Compact replaces consecutive runs of equal elements with a single copy. This is like the uniq command found on Unix. Compact modifies the contents of the slice s; it does not create a new slice. When Compact discards m elements in total, it might not modify the elements s[len(s)-m:len(s)]. If those elements contain pointers you might consider zeroing those elements so that objects they reference can be garbage collected.
func CompactFunc ¶
CompactFunc is like Compact but uses a comparison function.
func Contains ¶
func Contains[E comparable](s []E, v E) bool
Contains reports whether v is present in s.
func ContainsFunc ¶
ContainsFunc reports whether at least one element e of s satisfies f(e).
func Delete ¶
Delete removes the elements s[i:j] from s, returning the modified slice. Delete panics if s[i:j] is not a valid slice of s. Delete modifies the contents of the slice s; it does not create a new slice. Delete is O(len(s)-j), so if many items must be deleted, it is better to make a single call deleting them all together than to delete one at a time. Delete might not modify the elements s[len(s)-(j-i):len(s)]. If those elements contain pointers you might consider zeroing those elements so that objects they reference can be garbage collected.
func DeleteFunc ¶
DeleteFunc removes any elements from s for which del returns true, returning the modified slice. DeleteFunc modifies the contents of the slice s; it does not create a new slice. When DeleteFunc removes m elements, it might not modify the elements s[len(s)-m:len(s)]. If those elements contain pointers you might consider zeroing those elements so that objects they reference can be garbage collected.
func Equal ¶
func Equal[E comparable](s1, s2 []E) bool
Equal reports whether two slices are equal: the same length and all elements equal. If the lengths are different, Equal returns false. Otherwise, the elements are compared in increasing index order, and the comparison stops at the first unequal pair. Floating point NaNs are not considered equal.
func EqualFunc ¶
EqualFunc reports whether two slices are equal using a comparison function on each pair of elements. If the lengths are different, EqualFunc returns false. Otherwise, the elements are compared in increasing index order, and the comparison stops at the first index for which eq returns false.
func Grow ¶
Grow increases the slice's capacity, if necessary, to guarantee space for another n elements. After Grow(n), at least n elements can be appended to the slice without another allocation. If n is negative or too large to allocate the memory, Grow panics.
func Index ¶
func Index[E comparable](s []E, v E) int
Index returns the index of the first occurrence of v in s, or -1 if not present.
func Insert ¶
Insert inserts the values v... into s at index i, returning the modified slice. The elements at s[i:] are shifted up to make room. In the returned slice r, r[i] == v[0], and r[i+len(v)] == value originally at r[i]. Insert panics if i is out of range. This function is O(len(s) + len(v)).
