Module props

Expand description

This module defines all available properties.

Properties may be empty marker types and implement BinaryProperty, or enumerations¹ and implement EnumeratedProperty.

BinaryPropertys are queried through a CodePointSetData, while EnumeratedPropertys are queried through CodePointMapData.

In addition, some EnumeratedPropertys also implement ParseableEnumeratedProperty or NamedEnumeratedProperty. For these properties, PropertyParser, PropertyNamesLong, and PropertyNamesShort can be constructed.

either Rust enums, or Rust structs with associated constants (open enums) ↩
