Defined in:
lib/wireless.rb

Overview

Raised when an attempt is made to:

- retrieve a value from a key-indexed store when the key doesn't exist
- write a value when the key exists and the store doesn't allow replacements

Can be passed a message, the receiver the lookup failed on, and the key. All are optional and default to nil.

XXX eventually (i.e. in ruby 2.6), this can be a subclass of (or replaced by) the core KeyError class: bugs.ruby-lang.org/issues/14313
