Struct MappingSelection

struct MappingSelection<'a> {
    mapping_index: MappingIndex,
    codepoint_subtable: Option<SupportedSubtable<'a>>,
    variant_subtable: Option<Cmap14<'a>>,
}

The result of searching the cmap table for the “best” available subtables.

For codepoint_subtable, best means either symbol (which is preferred) or a Unicode subtable with the greatest coverage.

For variant_subtable, best means a format 14 subtable.

Fields

mapping_index: MappingIndex

The mapping index accelerator that holds indices of the following subtables.

codepoint_subtable: Option<SupportedSubtable<'a>>

Either a symbol subtable or the Unicode subtable with the greatest coverage.

variant_subtable: Option<Cmap14<'a>>

Subtable that supports mapping Unicode variation sequences.
