Struct Iso8601Formatter

pub struct Iso8601Formatter { /* private fields */ }

ISO 8601 / RFC 3339 date & time format.

Example:

2001-07-08T00:34:60.026490+09:30

Template:

• dt in the template would be the datetime string, similar to the above.
• mod_path, fn_name, level, and message all come out of the LogEntry provided to the format() method.

format!("{dt:35} |{mod_path}->{fn_name}| [{level:7}] {message}");

Sample output:

2025-07-18T14:01:01.051532664+08:00 |flogging->main| [WARNING] Rain is wet!
