Instance Method Details

#log_depth(options) { ... } ⇒ Object #log_depth ⇒ Integer

Overloads:

  • #log_depth(options) { ... } ⇒ Object

    Increase depth around a method invocation

    Options Hash (options):

    • :depth (Integer) — default: 1 —

      recursion depth

    • :logger (Logger, #<<)

    Yields:

    • Yields with no arguments

    Yield Returns:

    • (Object) —

      returns the result of yielding

  • #log_depth ⇒ Integer

    # Return the current log depth
