Function tr 

pub fn tr<I, O, E, F>(
    tag: &'static str,
    context: Option<&'static str>,
    name: &'static str,
    parser: F,
) -> impl FnMut(I) -> IResult<I, O, E>
where
    I: AsRef<str> + Clone,
    F: Parser<I, O, E>,
    O: Debug,
    E: TraceError<I>,

Main tracing function that wraps a parser with tracing functionality.

This function is the core of nom-tracer. It wraps a parser and adds tracing capabilities, recording the parser’s execution path and results.

Arguments

• tag - A static string used to categorize the trace events.
• context - An optional static string providing additional context for the trace.
• name - A static string identifying the parser being traced.
• parser - The parser function to be wrapped with tracing.
