Tracking Issue for std::fmt::Arguments::from_str

[m-ou-se]

Feature gate: #![feature(fmt_arguments_from_str)]

This is a tracking issue for std::fmt::Arguments::from_str.

Public API

// core::fmt

impl Arguments<'_> {
    pub const fn from_str(string: &'static str) -> Self;
}

Steps / History

• Implementation: New fmt::Arguments representation. #115129
• Final comment period (FCP)¹
• Stabilization PR

Unresolved Questions

• Are we comfortable committing to restricting future fmt::Arguments implementations by always having to support conversion from &'static str?
• Naming (new, new_const, new_str, ...?)
• Should this (also) be available as From<&'static str> implementation?
