[bjoernager]

Feature gate: #![feature(const_char_encode_utf16)]

This is a tracking issue for supporting char::encode_utf16 in const scenarios.

Public API

impl char {
    pub const fn encode_utf16(self, dst: &mut [u16]) -> &mut [u16];
}

Steps / History

• Implementation: Support char::encode_utf16 in const scenarios. #130659
• Final comment period (FCP)
• Stabilization PR: Stabilise const_char_encode_utf16. #132153

Unresolved Questions

• None yet.

[bjoernager]

I don't think char::decode_utf16 currently can be implemented as const due to its dependence on IntoIterator.
