Represents a decomposition mapping of a single row in the
UnicodeData.txt
file.
The formatting tag associated with this mapping, if present.
The number of codepoints in this mapping.
The codepoints in the mapping. Entries beyond len
in the mapping
are always U+0000. If no mapping was present, then this always contains
a single codepoint corresponding to this row's character.
Create a new decomposition mapping with the given tag and codepoints.
If there are too many codepoints, then an error is returned.
Add a new codepoint to this decomposition's mapping.
If the mapping is already full, then this returns an error.
Return the mapping as a slice of codepoints. The slice returned
has length equivalent to the number of codepoints in this mapping.
Returns true if and only if this decomposition mapping is canonical.
