Tracking Issue for const path separators

[MikkelPaulson]

Feature gate: #![feature(const_path_separators)]

This is a tracking issue for making platform-specific path separator information available in a const context. Currently the main separator is available via std::path::MAIN_SEPARATOR, but secondary separators, if any, are not available at compile time.

Public API

// std::path

/// was pub fn
pub const fn is_separator(c: char) -> bool;

/// supplements MAIN_SEPARATOR
pub const SEPARATORS: &[char];

/// supplements MAIN_SEPARATOR_STR
pub const SEPARATORS_STR: &[&str];
