pub struct ScriptWithExtensionsPropertyV1<'data> {
pub trie: CodePointTrie<'data, ScriptWithExt>,
pub extensions: VarZeroVec<'data, ZeroSlice<Script>>,
}
Expand description
A struct that efficiently stores Script
and Script_Extensions
property data.
Fields§
§trie: CodePointTrie<'data, ScriptWithExt>
Note: The ScriptWithExt
values in this array will assume a 12-bit layout. The 2
higher order bits 11..10 will indicate how to deduce the Script value and
Script_Extensions value, nearly matching the representation
in ICU:
High order 2 bits value | Script | Script_Extensions |
---|---|---|
3 | First value in sub-array, index given by lower 10 bits | Sub-array excluding first value, index given by lower 10 bits |
2 | Script=Inherited | Entire sub-array, index given by lower 10 bits |
1 | Script=Common | Entire sub-array, index given by lower 10 bits |
0 | Value in lower 10 bits | [ Script value ] single-element array |
When the lower 10 bits of the value are used as an index, that index is
used for the outer-level vector of the nested extensions
structure.
extensions: VarZeroVec<'data, ZeroSlice<Script>>
This companion structure stores Script_Extensions values, which are
themselves arrays / vectors. This structure only stores the values for
cases in which scx(cp) != [ sc(cp) ]
. Each sub-vector is distinct. The
sub-vector represents the Script_Extensions array value for a code point,
and may also indicate Script value, as described for the trie
field.
