Class Method Details

.from_hash(hash) ⇒ Tuber::StatStruct?

Convert a stats hash into a struct.

Examples:

s = StatStruct.from_hash(:foo => "bar")
s.foo # => 'bar'

Parameters:

  • hash (Hash{String => String}) —

    Hash Stats hash to convert to struct

Returns:

def self.from_hash(hash)
  return unless hash.is_a?(Hash)
  underscore_hash = hash.inject({}) { |r, (k, v)| r[k.to_s.gsub(/-/, '_')] = v; r }
  self.new(underscore_hash)
end

Instance Method Details

#[](key) ⇒ String, Integer

Access value for stat with specified key.

Keys are stored underscored (see from_hash), so hyphenated beanstalkd names like "current-jobs-ready" are underscored before lookup. This also avoids defining an invalid, hyphenated method name via method_missing.

Examples:

@stats['foo'] # => "bar"
@stats['current-jobs-ready'] # => 5

Parameters:

  • key (String) —

    Key to fetch from stats.

Returns:

  • (String, Integer) —

    Value for specified stat key.

def [](key)
  self.send(key.to_s.gsub(/-/, '_'))
end

#keys ⇒ Array<String>

Returns set of keys within this struct

Examples:

@stats.keys # => ['foo', 'bar', 'baz']

Returns:

  • (Array<String>) —

    Value for specified stat key.
