This function was adopted from [snailquote](https://docs.rs/snailquote/latest/snailquote/). # Details Parses a single or double quoted string and interprets escape sequences such as '\n', '\r', '\'', etc. Supports raw strings prefixed with `r` or `R` in which case all escape sequences are ignored./// The full set of supported escapes between quotes may be foun

(s: &str)

/// The returned result can display a human readable error if the string cannot be parsed as a
/// valid quoted string.
