Method find_member_position_in_class

src/definition/implementation.rs:1061–1096

Find a member position scoped to a specific class body. When multiple classes in the same file define a method with the same name, [`find_member_position`](Self::find_member_position) would always return the first match. This variant restricts the search to lines that fall within the class's `start_offset..end_offset` byte range so that each implementing class resolves to its own definition.

(
        content: &str,
        member_name: &str,
        kind: MemberKind,
        cls: &ClassInfo,
    )

    /// byte range so that each implementing class resolves to its own
    /// definition.
    fn find_member_position_in_class(
        content: &str,
        member_name: &str,
        kind: MemberKind,
        cls: &ClassInfo,
    ) -> Option<Position> {
        // Fast path: use stored AST offset when available.
        let name_offset = cls.member_name_offset(member_name, kind.as_str());
        if name_offset.is_some() {
            return Self::find_member_position(content, member_name, kind, name_offset);
        }

        // Convert byte offsets to line numbers.
        let start_line = content
            .get(..cls.start_offset as usize)
            .map(|s| s.matches('\n').count())
            .unwrap_or(0);
        let end_line = content
            .get(..cls.end_offset as usize)
            .map(|s| s.matches('\n').count())
            .unwrap_or(usize::MAX);

        // Build a sub-content containing only the class body lines and
        // delegate to the existing searcher, adjusting the result line.
        let class_lines: Vec<&str> = content
            .lines()
            .skip(start_line)
            .take(end_line - start_line + 1)
            .collect();
        let class_body = class_lines.join("\n");

            line: pos.line + start_line as u32,
            character: pos.character,
        })
    }
