Authenticates a req and returns a 401 Unauthorized using res if the authentication was not correct.
Authenticates a req and returns a 401 Unauthorized using res if the authentication was not correct.
Registers a new timeout handler
Returns the file name of this frame.
For example, using caller_locations.rb from Thread::Backtrace::Location
loc = c(0..1).first loc.path #=> caller_locations.rb
@return [Array<Vertex>] the vertices of {#graph} where ‘self` is a
{#descendent?}
@return [Array<Vertex>] the vertices of {#graph} where ‘self` is an
{#ancestor?}
@return [Object] the requirement that led to ‘requirement` being added
to the list of requirements.
Returns a new lazy enumerator with the concatenated results of running block once for every element in the lazy enumerator.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]
A value x returned by block is decomposed if either of the following conditions is true:
x responds to both each and force, which means that x is a lazy enumerator.
x is an array or responds to to_ary.
Otherwise, x is contained as-is in the return value.
[{a:1}, {b:2}].lazy.flat_map {|i| i}.force
#=> [{:a=>1}, {:b=>2}]
Like Enumerable#filter_map, but chains operation to be lazy-evaluated.
(1..).lazy.filter_map { |i| i * 2 if i.even? }.first(5) #=> [4, 8, 12, 16, 20]
Like Enumerable#drop_while, but chains operation to be lazy-evaluated.
