Function proc_macro_util::parse_keyed_strings

pub fn parse_keyed_strings(
    input: impl IntoIterator<Item = TokenTree>, 
    default_span: Span, 
    keys: &[&str]
) -> Result<HashMap<String, String>, SpanError>

Parse strings identified by keys

Argument

• input: token iterator to consume
• default_span: span to use when an error is detected but can't be linked to a span
• keys: keys to search for

Return

An hash map with the key that were detected with their associated value. The value contains the quote that makes the string literal.

Error

• When a key was detected but can't be parsed as a string literal assignment

Example

(my_val = "toto"), then the value of identifier my_valisr#""toto""#`.
