pub enum KeyMeaning {
Codepoint(u32),
NonPrintableKey(NonPrintableKey),
}
Expand description
The meaning of the key press. This is typically the Unicode codepoint inserted by this event, or an enum representing a key that corresponds to whitespace or is otherwise unprintable.
Variants§
Codepoint(u32)
The Unicode codepoint representing character typed, if any.
- In Dart and Go, this corresponds to a
rune
. - In Rust, this corresponds to a
char
. - In C and C++, this corresponds to ICU’s UChar32.
NonPrintableKey(NonPrintableKey)
The meaning of the key for key events with no corresponding symbol.
