FromString converts a string to a C4 ID.

LookupPrefix looks up id in map m by starting from the id itself, progressively taking a smaller and smaller prefix up to and including the empty ID, and returning the first value found.

MapGlob filters a string map m to those keys that match glob when interpreted as IDs.

MapKeys tries to get the keys of an ID-as-string map m as a sorted list.

New tries to construct a C4 ID from tags.

SearchSlice finds the smallest index in haystack for which the ID at that index is greater than or equal to needle.

Sort sorts ids.

TryFromString tries to convert a string to a C4 ID.
