Silences the tracing for a subtree of parsers.

This macro wraps a parser and prevents it and its sub-parsers from generating trace output. It’s useful for reducing noise in the trace output for well-tested or less interesting parts of your parser.

Usage

• silence_tree!(parser): Silences the default tag.
• silence_tree!(tag, parser): Silences a specific tag.
• silence_tree!("context", parser): Silences the default tag with a context.
• silence_tree!(tag, "context", parser): Silences a specific tag with a context.
