fn parse_string_value(value: &str) -> Option<String>Expand description
Parse a single-line TOML basic ("...") or literal ('...') string,
allowing a trailing # comment. Escape sequences in a basic string,
multi-line strings and non-string values return None. Unlike the macro
crate’s copy, a literal string keeps its backslashes (TOML has no escapes
there), so path = 'rust\lib.rs' reads as written.
