Method parse

assert-struct-macros/src/pattern/enum_pattern.rs:31–49

Parses an enum pattern with a required path prefix. # Example Input ```text Some(> 30) Event::Click(>= 0, < 100) Ok(== 42) Status::Active // Unit variant (no parens) ``` This assumes the input starts with a path, optionally followed by parenthesized content.

(input: ParseStream)

    /// This assumes the input starts with a path, optionally followed by parenthesized content.

        let path: syn::Path = input.parse()?;

        // Check if there are parentheses (tuple variant) or not (unit variant)
        let elements = if input.peek(syn::token::Paren) {
            let content;
            syn::parenthesized!(content in input);
            TupleElement::parse_comma_separated(&content)?
        } else {
            // Unit variant - no elements
